Organic Framework

A heterometallic metal−organic framework (MOF) of [Cd6Ca4(BTB)6(HCOO)2(DEF)2(H2O)12]∙DEF∙xSol (1, H3BTB = benzene-1,3,5-tribenzoic acid; DEF = N,N′-diethylformamide; xSol. = undefined solvates within the pore) was prepared by solvothermal reaction of Cd(NO3)2·4H2O, CaO and H3BTB in a mixed solvent of DEF/H2O/HNO3. The compatibility of these two divalent cations from different blocks of the periodic table results in a solid-state structure consisting of an unusual combination of a discrete V-shaped heptanuclear cluster of [Cd2Ca]2Ca′ and an infinite one-dimensional (1D) chain of [Cd2CaCa′]n that are orthogonally linked via a corner-shared Ca2+ ion (denoted as Ca′), giving rise to an unprecedented branched-chain secondary building unit (SBU). These SBUs propagate via tridentate BTB to yield a three-dimensional (3D) structure featuring a corner-truncated P41 helix in MOF 1. This outcome highlights the unique topologies possible via the combination of carefully chosen s- and d-block metal ions with polydentate ligands.

Organic Framework

A unique 3D fourfold interpenetrated metal-organic framework, [Co(L)(H2O)2]・H2O (1), has been synthesized by the solvothermal reaction of H2L with Co(NO3)2・6H2O (H2L = 5-(isonicotinamido) isophthalic acid). Compound 1 crystallizes in the monoclinic space group P21/c, with the cell parameters: a = 81301(8), b = 107711(11), c = 167697(16) Å , β = 92.656(2) °, V = 14669(3) Å3, R1 = 0.0325 and wR2 = 0.0833. Its framework has (10,3)-b topology, where the cobalt atoms are alternately bridged by the pyridyl and the carboxylate groups of the L2− ligands into a three-dimensional network. Compound 1 displays antiferromagnetic interactions. Above 40 K, χm −1 obeys the Curie- Weiss law with C = 3.28 emu Kmol−1 andΘ = −0.66 K.

Organic Framework

A polydentate ligand bridged by a fluorene group, namely 9,9-bis(2-hydroxyethyl)-2,7-bis(pyridin-4-yl)fluorene (L), has been prepared under solvothermal conditions in acetonitrile. Crystals of the three-dimensional metal–organic framework (MOF) poly[[[μ3-9,9-bis(2-hydroxyethyl)-2,7-bis(pyridin-4-yl)fluorene-κ3 N:N′:O]bis(methanol-κO)(μ-sulfato-κ2 O:O′)nickel(II)] methanol disolvate], {[Ni(SO4)(C27H24N2O2)(CH3OH)]·2CH3OH} n , (I), were obtained by the solvothermal reaction of L and NiSO4 in methanol. The ligand L forms a two-dimensional network in the crystallographic bc plane via two groups of O—H...N hydrogen bonds and neighbouring two-dimensional planes are completely parallel and stack to form a three-dimensional structure. In (I), the NiII ions are linked by sulfate ions through Ni—O bonds to form inorganic chains and these Ni-containing chains are linked into a three-dimensional framework via Ni—O and Ni—N bonds involving the polydentate ligand L. With one of the hydroxy groups of L coordinating to the NiII atom, the torsion angle of the hydroxyethyl group changes from that of the uncoordinated molecule. In addition, the adsorption properties of (I) with carbon dioxide were investigated.

In (I), the two unique AgIcations have AgNI3and AgI4four-coordinated tetrahedral geometries. The bmimp ligand has imposed twofold symmetry. The AgIcations and iodide anions form a unique one-dimensional polymeric column motif incorporating [Ag6I6] hexagonal prisms, which are then connected by bmimp ligands to form two-dimensional organic–inorganic layers. The layers are arranged in parallel in anABABfashion and are packed into the resultant three-dimensional supramolecular framework by van der Waals interactions.

The solvothermal reaction of MnCl2·H2O and 5-methoxybenzene-1,3-dicarboxylic acid (MeO-m-H2BDC) led to a three-dimensional MnIImetal–organic framework, namely poly[(dimethylformamide-κO)(μ4-5-methoxybenzene-1,3-dicarboxylato-κ4O1:O1′:O3,O3′:O3)manganese(II)], [Mn(C9H6O5)(C3H7NO)]nor [Mn(MeO-m-BDC)(DMF)]n(DMF is dimethylformamide). The MnIIatom is six-coordinated and exhibits a distorted octahedral geometry formed by five carboxylate O atoms from four different MeO-m-BDC2−anionic ligands and by one DMF O atom. The three-dimensional framework of (I) formed by the bridging MeO-m-BDC2−ligands and the MnIIatoms exhibits aptstopological network when MeO-m-BDC2−and MnIIare viewed as four-connected nodes.
