摘要
Two zinc(II) complexes, namely [Zn(tmphen)2(H2odpa)]center dot 0.88H2O (1) and [Zn(tmphen)2(H2odpa)]n (2) (tmphen = 3,4,7,8-tetramethyl-1,10-phenanthroline, H4odpa = 4,4-oxydiphthalic acid), have been successfully synthesized at different pH values under hydrothermal conditions. In complex 1, the mononuclear [Zn(tmphen)2(H2odpa)]center dot 0.88H2O units are bridged by hydrogen bonds and CH center dot center dot center dot interactions. In 2, H2odpa2 ligands act as bridges between neighboring Zn atoms to form a one-dimensional chain. The structural diversities of 1 and 2 reveal that the pH value of the reaction system plays a crucial role in the assembly of coordination polymer solids.
