摘要

Four compounds [Dy(H2bidc)(Hbidc)(H_2O)_8] ·8H_2O (1), {[Dy(Hbidc)(H_2O)_2(Htzac)] ·3H_2O}_n (2), [Dy(C_2O_4) _(0.5)(Hbidc)(H_2O)_3]_n (3), {[Dy _2(Hbidc)_2(H_2O)(SO_4)] ·H _2O}_n (4) (H_3bidc = 1H-benzimidazole-5,6- dicarboxylic acid, H_2tzac = 1H-3-amino-5-carboxy-1,2,4-triazole) were synthesized with hydrothermal synthesis and structurally characterized by elemental analysis, IR spectroscopy, and single-crystal X-ray diffraction. X-ray analysis revealed that the four coordination compounds have different structures: Compound 1 is a three dimensional supermolecular structure joined by hydrogen bonding interactions based upon dinuclear units. Compound 2 is a three dimensional supermolecular structure combined by hydrogen-bonding interactions based upon one dimensional coordination chain including a T4(1)-type water cluster chain. The structure of compound 3 is built of two dimensional (3,6)-connected kgd-type (4~3)_2(4~6.6 ~6.8~3) layers with a right-handed and a left-handed helical chain, which are further extended into three dimensional supramolecular architecture by hydrogen bonding interactions. Compound 4 displays a three dimensional framework containing a dinuclear dysprosium building unit with a (3,8)-connected (4.5~2)_2(4~2.5 ~(10).6~(12).7.8~3) topological framework. In addition, the photoluminescent property of compound 3 was investigated.
