Two new coordination polymers, namely poly[[(3-aminopyrazin-4-ium-2-carboxylate-κ2 N 1,O)di-μ-chlorido-cadmium(II)] monohydrate], {[CdCl2(C5H5N3O2)]·H2O} n , (1), and poly[2-amino-3-carboxypyrazin-1-ium [(3-aminopyrazine-2-carboxylato-κ2 N 1,O)di-μ-chlorido-cadmium(II)] monohydrate], {(C5H6N3O2)[Cd(C5H4N3O2)Cl2]·H2O} n , (2), have been synthesized from the reaction of cadmium(II) chloride and 3-aminopyrazine-2-carboxylic acid (Hapca) under mild conditions in acidic media. The two coordination polymers have been characterized by single-crystal X-ray diffraction and show chloride-bridged zigzag chains with octahedrally coordinated metal ions, where Hapca acts as a bidentate ligand via the π-conjugated N atom and a carboxylate O atom. The chains are further interconnected via noncovalent interactions into three-dimensional supramolecular networks. The dominant H...O and H...Cl interactions for both compounds were quantified using Hirshfeld surface analysis. The thermal stability and topological analysis of the two-dimensional networks of (1) and (2) are also discussed.

The design and synthesis of coordination polymers with a self-penetrating architecture has attracted much interest not only due to their interesting structures but also due to their potential applications. 5,5′-Bis(pyridin-4-yl)-2,2′-bithiophene (bpbp), as a conjugated bithiophene ligand, can exhibit trans and cis conformations and this can lead to the construction of a self-penetrating architecture. In addition, the semi-rigid ancillary ligand 4,4′-oxybis(benzoic acid) (H2oba) can adopt different coordination modes, resulting in coordination polymers with high-dimensional skeletons. A new CdII coordination polymer based on mixed ligands, namely poly[diaquapentakis[μ-5,5′-bis(pyridin-4-yl)-2,2′-bithiophene-κ2 N:N′]bis(nitrato-κ2 O,O′)tetrakis(μ3-4,4′-oxydibenzoato)-κ10 O:O,O′:O′′,O′′′;κ6 O:O′:O′′-pentacadmium(II)], [Cd5(C14H14O5)4(NO3)2(C18H12N2S2)5(H2O)2] n , (I), has been synthesized under solvothermal conditions and characterized by single-crystal X-ray diffraction, IR spectroscopy and elemental analysis. Single-crystal X-ray diffraction indicates that there are three crystallographically independent CdII cations, three bpbp ligands, two deprotonated oba2− ligands, one nitrate ligand and one coordinated water molecule in the asymmetric unit. One CdII centre is seven-coordinated, exhibiting a distorted {CdN2O5} pentagonal bipyramidal geometry, while the other two Cd centres are both six-coordinated, showing slightly distorted {CdN2O4} octahedral geometries. The most interesting feature is the co-existence of trans and cis conformations in a single net, allowing structural interpenetration via self-threading and yet the expected self-penetrating structure was obtained. Topological analysis shows that the whole three-dimensional framework can be classified as a 3-nodal (4,6,6)-c net with Schläfli symbol {613.82}2{66}, which is a new topology. Furthermore, the luminescence properties of (I) were examined in the solid state at room temperature.

Opening Up

Two new 3D coordination polymers (CPs), formulated as [Zn(p-XBT)]n (1H) and [Cd(p-XBT)]n (2H), were assembled from a virtually unexplored p-xylylene-bis(2-mercaptoacetic) acid linker (p-XBTA) and characterized by infrared spectroscopy (FTIR), powder X-ray diffraction (PXRD), thermal analysis methods (TG-DSC, TG-FTIR), single-crystal X-ray diffraction, and topological analysis. Two different synthetic strategies were explored, namely the precipitation (P) and hydrothermal (H) methods, resulting in a Zn(II) derivative [Zn(p-XBT)·H2O]n (1P) and its dehydrated analogue [Zn(p-XBT)]n (1H), respectively. In the Cd(II)-containing system, the same [Cd(p-XBT)]n (2P = 2H) products were generated by both synthetic methods. Upon dehydration, 1P undergoes a “crystal-to-crystal” phase transition in the 170−185 °C temperature range, producing an anhydrous polycrystalline sample (1H). Both CPs 1H and 2H are isostructural and feature polymeric 3D metal-organic nets of the cds topological type, which are driven by the 4-linked metal and p-XBT2− nodes. These compounds represent unique examples of coordination polymers derived from p-xylylene-bis(2-mercaptoacetic) acid, thus opening up the use of this flexible S,O-heterodonor building block in the design of polymeric metal-organic architectures.

Two new one-dimensional (1D) coordination polymers (CPs), namely catena-poly[[[aquacadmium(II)]-bis(μ-4b,5,7,7a-tetrahydro-4b,7a-epiminomethanoimino-6H-imidazo[4,5-f][1,10]phenanthroline-6,13-dione)] bis(perchlorate) dihydrate], {[Cd(C14H10N6O2)2(H2O)](ClO4)2·2H2O} n or {[Cd(BPG)2(H2O)](ClO4)2·2H2O} n , 1, and catena-poly[[lead(II)-bis(μ-4b,5,7,7a-tetrahydro-4b,7a-epiminomethanoimino-6H-imidazo[4,5-f][1,10]phenanthroline-6,13-dione)] bis(perchlorate) dihydrate], {[Pb(C14H10N6O2)2](ClO4)2·2H2O} n or {[Pb(BPG)2](ClO4)2·2H2O} n , 2, have been synthesized using bipyridine–glycoluril (BPG; systematic name: 4b,5,7,7a-tetrahydro-4b,7a-epiminomethanoimino-6H-imidazo[4,5-f][1,10]phenanthroline-6,13-dione), a urea-fused tecton, in a mixed-solvent system. The CdII ion in 1 is heptacoordinated and the PbII ion in 2 is hexacoordinated, with the CdII ion adopting a pentagonal bipyramidal geometry and the PbII ion adopting a distorted octahedral geometry. Both CPs form infinite linear chain structures which are hydrogen bonded to each other leading to the formation of three-dimensional supramolecular network structures. Topological analysis of CPs 1 and 2 reveals that the structures exhibit 1D chain-like arrangements in an AB–AB sequence and shows platonic uniform 2-connected uninodal topologies. Furthermore, a comparative analysis of a series of structures based on the BPG ligand indicates that the size of the metal ion and the types of counter-ions used have a great influence on the resulting frameworks and properties.
