摘　　要：通过水热合成的方法制备了2个Zn(Ⅱ)配位聚合物{[Zn_(1.5)(dbim)_(1.5)(btc)]·6H_2O}_n(1)和{[Zn(dbim)_(0.5)(btec)_(0.5)(H_2O)]·H_2O}_n(2)(dbim=1-(4-((2,6-dimethyl-2H-benzo[d]imidazol-3(3H)-yl)methyl)benzyl)-2,7-dihydro-2,5-dimethyl^(-1)H-benzo[d]imidazole,H_3btc=1,3,5-苯三酸,H_4btec=1,2,4,5-苯四甲酸)。结构分析表明配合物1是一个三节点(3,4,4)-连接的网络,拓扑符号为(5~2·6·7·8~2)(5~2·6)(5~2·6~2·8~2)。配合物2是一个(3,4)-连接的网络,拓扑符号为(8~3)(8~5·10)。配合物1和2的固态荧光与配体dbim不同。Two Zn(Ⅱ)coordination complexes, formulated as {[Zn1.5(dbim)1.5(btc)]·6H2O}n (1) and {[Zn(dbim)0.5(btec)0.5 (H2O)]·H2O}n (2)(dbim=1-(4-((2,6-dimethyl-2H-benzo[d]imidazol-3(3H)-yl)methyl)benzyl)-2,7-dihydro-2,5-dimethyl- 1H-benzo[d]imidazole, H3btc=trimesic acid, H4btec=1,2,4,5-benzene tetracarboxylic), have been obtained by hydrothermal reactions. Complex 1 is a trinodal (3,4,4)-connected topology net with the point symbol of (5^2·6·7· 8^2)(^52·6)(5^2·6^2·8^2), while complex 2 possesses a (3,4)-connected 3D topology with the point symbol of (8^3)(8^5·10) topology. Additionally, complexes 1 and 2 exhibit different photoluminescence behaviors in solid state compared to ligand dbim. CCDC:1584788, 1;1584789, 2.
