摘要
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.
