Five new Cu(ii) complexes have been prepared by employing 2,3-naphthalenedicarboxylic acid (H2ndc) and different N-donor co-ligands, namely, [Cu(ndc)(H2O)]n (1), [Cu(ndc)(H2O)2]n (2), {[Cu1.5(ndc)(OH)(H2O)2]·2.5H2O}n (3), {[Cu(ndc)(phen)(H2O)]·CH3OH}n (4) (phen = 1,10-phenanthroline), and {[Cu2(H0.5ndc)2(4bpy)3](ClO4)·2H2O}n (5) (4bpy = 4,4′-bipyridine). Complex 1 displays a two-dimensional (2D) (4,6)-connected (32.44)2(34.42.64.75)(34.43.64.74) coordination network. Complex 2 shows a 2D 3-connected hcb network which is further interlinked via the interlayered C–H⋯π interactions to result in a three-dimensional (3D) supramolecular network. Complex 3 is a one-dimensional (1D) coordination chain which is further interlinked by the C–H⋯π and π⋯π interactions to lead to the formation of the final 3D supramolecular network. When the N-donor co-ligands phen and 4,4′-bipyridine (4bpy) were introduced, the 1D complex 4 and the 4-connected sql layered complex 5 were constructed, respectively. The final supramolecular frameworks of 4 (2D) and 5 (3D) are extended by hydrogen-bonding and C–H⋯π interactions. The structural diversity of the complexes was triggered by different reaction conditions and N-donor co-ligands. Moreover, the magnetic properties of the complexes have also been investigated and discussed.

The title compound, {[Co(H2O)6][Co(SO4)(C10H8N2)(H2O)3][Co(SO4)2(C10H8N2)(H2O)2]}n, contains three crystallographically unique CoIIcentres, all of which are in six-coordinated environments. One CoIIcentre is coordinated by two bridging 4,4′-bipyridine (4,4′-bipy) ligands, one sulfate ion and three aqua ligands. The second CoIIcentre is surrounded by two N atoms of two 4,4′-bipy ligands and four O atoms,i.e.two O atoms from two monodentate sulfate ions and two from water molecules. The third CoIIcentre forms part of a hexaaquacobalt(II) ion. In the crystal structure, there are two different one-dimensional chains, one being anionic and the other neutral, and adjacent chains are arranged in a cross-like fashion around the mid-point of the 4,4′-bipy ligands. The structure features O—H...O hydrogen-bonding interactions between sulfate anions and water molecules, resulting in a three-dimensional supramolecular network.

The compound crystallizes in the monoclinic space groupC2/c(data collected at 273 K). In the crystal structure, neighbouring [Co(CN)6]3−anionic units are linked by Li+cations through the cyanide groups in atransmode, forming a one-dimensional zigzag chain structure extending along thecaxis. A three-dimensional supramolecular network is formed through hydrogen-bonding interactions and is further stabilized by weak CN...π interactions between the cyanide groups and the imidazolium cations.

A new iodate Er(IO3)3·2H2O was synthesized under mild hydrothermal conditions. The structure has been confirmed by single-crystal X-ray analysis. It crystallizes in the triclinic system with space group P-1 (No.2), a = 7.338(4) Å, b = 7.506(4) Å, c = 9.409(5) Å, α = 79.698(5)°, β = 85.245(4)°, γ = 71.934(4)°, V = 484.5(5) Å3, Z = 2. Some characterizations were performed such as Fourier transform infrared spectroscopy (FTIR), thermogravimetric–differential scanning calorimetry (TG-DSC) analysis, luminescence spectroscopy, and magnetic property measurements. The overall framework of Er(IO3)3·2H2O is based on one-dimensional chains. The adjacent chains are further linked with each other by hydrogen bonds to form a three-dimensional supramolecular network. The luminescent and magnetic properties of Er(IO3)3·2H2O were studied.

Coordination polymers (CPs) built by coordination bonds between metal ions/clusters and multidentate organic ligands exhibit fascinating structural topologies and potential applications as functional solid materials. The title coordination polymer, poly[diaquabis(μ4-biphenyl-3,4′,5-tricarboxylato-κ4O3:O3′:O4′:O5)tris[μ2-1,4-bis(1H-imidazol-1-yl)benzene-κ2N3:N3′]dicopper(II)dicopper(I)], [CuII2CuI2(C15H7O6)2(C12H10N4)3(H2O)2]n, was crystallized from a mixture of biphenyl-3,4′,5-tricarboxylic acid (H3bpt), 1,4-bis(1H-imidazol-1-yl)benzene (1,4-bib) and copper(II) chloride in a water–CH3CN mixture under solvothermal reaction conditions. The asymmetric unit consists of two crystallographically independent Cu atoms, one of which is CuII, while the other has been reduced to the CuIion. The CuIIcentre is pentacoordinated by three O atoms from three bpt3−ligands, one N atom from a 1,4-bib ligand and one O atom from a coordinated water molecule, and the coordination geometry can be described as distorted trigonal bipyramidal. The CuIatom exhibits a T-shaped geometry (CuN2O) coordinated by one O atom from a bpt3−ligand and two N atoms from two 1,4-bib ligands. The CuIIatoms are extended by bpt3−and 1,4-bib linkers to generate a two-dimensional network, while the CuIatoms are linked by 1,4-bib ligands, forming one-dimensional chains along the [20\overline{1}] direction. In addition, the completely deprotonated μ4-η1:η1:η1:η1bpt3−ligands bridge one CuIand three CuIIcations along thea(or [100]) direction to form a three-dimensional framework with a (103)2(10)2(42.6.102.12)2(42.6.82.10)2(8) topologyviaa 2,2,3,4,4-connected net. An investigation of the magnetic properties indicated a very weak ferromagnetic behaviour.

In the title one-dimensional coordination polymer, [Mn(NCS)3(C10H16N3)]n, the MnIIatom is coordinated by anN,N′-bidentate Schiff base and four thiocyanate ligands in a distorted octahedral N5S geometry. Bridging thiocyanate ligands interconnect adjacent [Mn(NCS)2(C10H16N3)] units, giving rise to helical chains extending along thebaxis. The chains are further linked through N—H...S hydrogen bonds, leading to a three-dimensional supramolecular network.

A new tetrazole–metal supramolecular compound, di-μ-chlorido-bis(trichlorido{1-[(1H-tetrazol-5-yl-κN2)methyl]-1,4-diazoniabicyclo[2.2.2]octane}cadmium(II)), [Cd2(C8H16N6)2Cl8], has been synthesized and structurally characterized by single-crystal X-ray diffraction. In the structure, each CdIIcation is coordinated by five Cl atoms (two bridging and three terminal) and by one N atom from the 1-[(1H-tetrazol-5-yl)methyl]-1,4-diazoniabicyclo[2.2.2]octane ligand, adopting a slightly distorted octahedral coordination geometry. The bridging bicyclo[2.2.2]octane and chloride ligands link the CdIIcations into one-dimensional ribbon-like N—H...Cl hydrogen-bonded chains along thebaxis. An extensive hydrogen-bonding network formed by N—H...Cl and C—H...Cl hydrogen bonds, and interchain π–π stacking interactions between adjacent tetrazole rings, consolidate the crystal packing, linking the poymeric chains into a three-dimensional supramolecular network.

Three new dicyanamide-bridged polymeric complexes of{[Mn(dca)2(L)2]·2H2O}n(1),{[Cd(dca)2(L)2]·2H2O}n(2), and{[Co(dca)2(L)2]2(L)}n(3) (dca = dicyanamide, L = pyridinium-4-olate) have been synthesized and structurally characterized. In the three compounds, the protons of hydroxyl groups of 4-hydroxypyridine transfer to pyridyl nitrogen atoms. Compounds1and2are isomorphous forming one-dimensional[M(dca)2(L)2]nchains where metals are connected by double dca anions. These one-dimensional chains are extended into two-dimensional layers through weak C–H⋯N hydrogen bonds. Further, these layers are assembled into a three-dimensional supramolecular network through N–H⋯O, O–H⋯O hydrogen bonds. Complex3is a coordination layer of (4, 4) topology with octahedral metal centers linked by four singleμ1,5-bridges. These layers are interlocked by N–H⋯O, O–H⋯O hydrogen bonds from coordinated water molecules and free L molecules, which leads to a three-dimensional supramolecular architecture. The variable temperature magnetic susceptibilities measurement of compounds1and3shows the existence of weak antiferromagnetic interactions between the metal centers. The thermogravimetric analyses of the compounds1–3are also discussed.
