Synthesis, topology analysis and luminescent property of a 3D AgCN coordination polymer based on 2-tptz (2-tptz = 2,4,6-tri(2-pyridyl)-1,3,5-triazin)

The solvothermal reaction of AgCN with 2-tptz (2-tptz = 2,4,6-tri(2-pyridyl)-1,3,5-triazin) afforded a 3D coordination polymer [(AgCN)3(2-tptz)]n (1). It was characterized by infrared spectroscopy, elemental analysis and X-ray single-crystal analysis. The structure of this polymer features a 2D wavelike [AgCN]n substructure constructed from 18-membered of Ag6(CN)6 rings and 22-membered of Ag8(CN)6C2 rings. When silver⋯sliver interactions are taken into account, the structure of 1 exhibits a (3 · 8 · 9)(4 · 8 · 9)(3 · 4 · 8 · 93)(3 · 8 · 92 · 102) topological network which has not been reported for the (3, 4)-connected nets. The photoluminescent property of the present coordination polymer was also investigated.
