【摘要】 通过水热合成的方法制备了2个Zn(Ⅱ)配位聚合物{[Zn1.5(dbim)1.5(btc)]·6H2O}n(1)和{[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=1,3,5-苯三酸,H4btec=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(52·6·7·82)(52·6)(52·62·82)。配合物2是一个(3,4)-连接的网络,拓扑符号为(83)(85·10)。配合物1和2的固态荧光与配体dbim不同。

【Abstract】 Two Zn(Ⅱ) coordination complexes, formulated as {[Zn1.5(dbim)1.5(btc)]·6 H2 O}n(1) and {[Zn(dbim)0.5(btec)0.5(H2 O)]·H2 O}n(2)(dbim=1-(4-((2,6-dimethyl-2 H-benzo[d]imidazol-3(3 H)-yl)methyl)benzyl)-2,7-dihydro-2,5-dimethyl-1 H-benzo[d]imidazole, H3 btc=trimesic acid, H4 btec=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(52·6·7·82)(52·6)(52·62·82), while complex 2 possesses a(3,4)-connected 3 D topology with the point symbol of(83)(85·10)topology. Additionally, complexes 1 and 2 exhibit different photoluminescence behaviors in solid state compared to ligand dbim.
