Hydrogen-Bonded Three-Dimensional Molecular Architectures Featuring Carboxylate–Imidazole–Zinc Triad Systems

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