摘要：
The two new compounds [Zn(Him)(2)(oda)](n) (1) and [Cd-2(Him)(4)(oda)(2)(H2O)](2). 6H(2)O (2) (Him=imidazol, oda=oxydiacetate) have been prepared and their structures determined by single-crystal X-ray diffraction studies. Compound 1 consists of polymeric chains formed by ZnN2O2 tetrahedral units bridged by the carboxylate groups of extended oda ligands; 2 is tetranuclear with the cadmium atoms in pentagonal bipyramidal CdN2O5 coordination geometry. The extended structures and the hydrogen-bonding patterns displayed by both the compounds were examined. (C) 1999 Elsevier Science S.A. All rights reserved.
