摘要 A new zinc coordination polymer {[Zn2(ttmb)2(dca)4(H2O)].H2O}n (1.H2O) was synthesized by the reaction of 1,3,5-tris(1,2,4-triazol-1-ylmethyl)benzene (ttmb), Zn(II) salt and sodium dicyanamide (Na(dca)). The structure of the title compound was determined by single-crystal X-ray diffraction, elemental analyses and IR spectra. 1 exhibits a (3,4)-connected 2D double-layer network with the point symbol of {63}{(66}. The solid-state luminescence shows a strong emission band at 485 nm upon excitation at 384 nm. The thermal stability properties were also studied.

Abstract： A new zinc coordination polymer {[Zn2(ttmb)2(dca)4(H2O)].H2O}n (1.H2O) was synthesized by the reaction of 1,3,5-tris(1,2,4-triazol-1-ylmethyl)benzene (ttmb), Zn(II) salt and sodium dicyanamide (Na(dca)). The structure of the title compound was determined by single-crystal X-ray diffraction, elemental analyses and IR spectra. 1 exhibits a (3,4)-connected 2D double-layer network with the point symbol of {63}{(66}. The solid-state luminescence shows a strong emission band at 485 nm upon excitation at 384 nm. The thermal stability properties were also studied.
