Three-dimensional framework eopper(1) coordination polymer with cuprous chloride, and 3-(pyridin-2-yl)-l,2,4-triazole, has been hydrothermally synthesized. Crystal data for this complex: Monoclinic, space group P2 1/n, 0=1.203 3(2) nm, 6 = 1.289 1(3) nm, c=1.582 3(3) nm, 7=2.338(8) nm3, Dc =1.779 g-cm-3, Z=4, F(000)=1248. GooF = 1.060, Ri=0.026 6, wR2=0.064 0. The asymmetric structural unit contains three copper atoms and three ligands. Copper ion is coordinated with four nitrogen atoms, forming a distorted tetrahedron. The result of fluorescence spectrum analysis shows that the title complex ...
