摘要
The three-dimensional framework copper(II) coordination polymer with basic copper carbonate and 3-(pyridin-2-yl)-1,2,4-triazole has been hydrothermally synthesized. It crystallizes in monoclinic space group P2(1)/c, with a = 1.20860(3), b = 1.29581(2), c = 1.67863(3) nm, beta = 116.0280(2)degrees, C21H12Cu3N12, M-r = 623.05, V = 2.36230(9) nm(3), D-c = 1.752 g/cm(3), Z = 4, F(000) = 1236, GOOF = 1.037, the final R = 0.0408 and wR = 0.1141. Every unit cell contains three copper atoms and three 3-(pyridin-2-yl)-1,2,4-triazole ligands. Every central Cu(II) ion is coordinated by four nitrogen atoms of the 3-(pyridin-2-yl)-1,2,4-triazole ligands, forming a distorted tetrahedron. The title complex exhibits an intense photoluminescence at room temperature with the maximum emission at 392 nm. The cyclic voltametric behavior of the complex shows that the electron transfer in electrolysis reaction is irreversible.
