摘要：

Two complexes, [Zn(Him)(2)(mpa)] (1) and [Zn(Him)(2)(tpa)].H2O (2) (Him = imidazole, mpa = m-phthalate, and tpa = terephthalate), have been prepared and structurally characterized, revealing two different three-dimensional hydrogen-bonded molecular architectures. Each features [Zn(Him)(2)(dicarboxylate)] zigzag polymeric chains and intermolecular N-H...O hydrogen bonds between the uncoordinated Him nitrogen atoms and carboxylate oxygen atoms that are similar to the carboxylate-histidine-zinc triad systems in zinc(II) enzymes. The lattice water molecules in complex (2) play a critical role in the formation of a three-dimensional hydrogen-bonded molecular architecture.
