摘要
A novel CdII metalorganic framework, [Cd(C3H2O4)(NH3)](n), was synthesized by liquid diffusion conducted in the presence of ammonia. The CdII atom has seven-coordinate O6N pentagonalbipyramidal geometry. Six CdII centers are joined by six malonate ligands to form an S6-symmetric [Cd-6(malonate)(6)] metallomacrocycle, which is further extended through a side-on chelating malonate ligand to form a three-dimensional network. Topologically, each CdII center is connected to four others to yield an infinite three-periodic four-coordinated SOD (sodalite) network with point symbol {42 center dot 64}. The overall network structure in the crystal is maintained and stabilized by the presence of N-H...O hydrogen bonds.
