Synthesis and structures of two new metal-organic polymers containing imidazoldicarboxylate ligands for hydrogen bonding networks, one with a covalent pleated sheet conformation

摘要

The reactions of Cd(NO3)(2) (.) 4H(2)O with imidazol-4,5-dicarboxylic acid and 4,4'-bipyridine under hydrothermal reaction conditions resulted in two metal-organic polymers [(H2O)(2)Cd(H2IDC)2] (.) BPY (1) and [(H2O)(2)Cd-2(HIDC)(2)BPY] (2). The compound 1 has a three-dimensional (3D) hydrogen-bonding network. The hydrogen-bonding linked 3D structure of complex 2 composed of covalent pleated sheets. (C) 2004 Elsevier B.V. All rights reserved.
