Organic Framework

A novel CdIImetal–organic framework, [Cd(C3H2O4)(NH3)]n, was synthesized by liquid diffusion conducted in the presence of ammonia. The CdIIatom has seven-coordinate O6N pentagonal–bipyramidal geometry. Six CdIIcenters are joined by six malonate ligands to form anS6-symmetric [Cd6(malonate)6] metallomacrocycle, which is further extended through a side-on chelating malonate ligand to form a three-dimensional network. Topologically, each CdIIcenter is connected to four others to yield an infinite three-periodic four-coordinated SOD (sodalite) network with point symbol {42·64}. The overall network structure in the crystal is maintained and stabilized by the presence of N—H...O hydrogen bonds.

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.
