Synthesis, Crystal Structure, and Properties of a 3D Cu(I) Coordination Polymer Based on Cu3(CN)2 Clusters and 1,3-Di-(1,2,4-Triazole-4-yl)Benzene

A new coordination polymer, [Cu3(dtb)(CN)3]n (1) (dtb = 1,3-di-(1,2,4-triazole-4-yl)benzene) based on Cu3(CN)2 clusters, has been synthesized under solvothermal conditions, and characterized by elemental analysis, infrared spectrometry, powder X-ray diffraction, thermogravimetric analysis, and single-crystal X-ray diffraction. Complex 1 exhibits a three-dimensional twofold interpenetrated net with 6-connected uninodal topology. Moreover, solid state luminescent property of 1 has been investigated at room temperature.
