The self-assembly of big molecules has been well established in biological systems. In addition, the coordination chemistry of metal-sulfur-nitrogen cluster complexes has been a very active and attracting field for many years as a result of the novelty and versatility of the crystal structures and reactivities of such clusters, as well as their potential applications as the models for the active sites in non-heme proteins. At the same time, there is currently considerable interest in the formation of metal complexes with heterocyclic ligands because of the diverse characteristics of ligands and their consequential wide range of applications.展开更多
A novel 2D coordination polymer [Zn2（bim）4]n（1）（Hbim=benzimidazole） based on dihydrated- [N,N＇-bis（2-aminophenl）-oxalamide]（L1·2H2O） with zinc nitrate has been synthesized.

Previously we have synthesized complexes [In：Zn3（im）12]n（2）（Him= imidazole） and [Zn（im）2]n（3） successfully. In complex 1, each Zn（Ⅱ） coordinated with four ligands adopts a distorted tetrahedron coordination mode, and the 2D grid structure is built by the Zn（bim）4 as the secondary building unit（SBU）. The luminescence properties of the three complexes were investigated for the first time. The emissions with maxima for complexes 1, 2 and 3 are at 379, 469 and 392 nm, respectively.展开更多
