copper(Ⅱ) complex%synthesis%crystal structure%1-D chain
The title complex, [Cu(L)Cl2]n (L = 2,5-di-2-pyridyl-1,3,4-oxodiazole) 1, has mixture solvent of CH3CN and CH2Cl2 (L is generated from the metal-assisted hydrolysis reaction of bptz) and structurally characterized. It crystallizes in space group C2/c of monoclinic system with cell parameters: a = 9.812(2), b = 12.679(3), c = 1 1.111(2) A, β = 103.92(3)°, V = 1341.6(5)A3, Z = 4, Dc = 1.776 g/cm3, Mr= 358.66, F(000) = 716, μ = 2.024 mm-1 and S = 1.004. The final R = 0.0346 and wR = 0.0938 for 1011 observed reflections with I ＞ 2σ(I). The Cu( Ⅱ ) ion is six-coordinated by four N atoms of two L ligands and two Cl- ions in a distorted octahedral geometry. The ligand L acts as a bis-bidentate ligand to bridge the Cu( Ⅱ ) ions, resulting in an infinite chain structure.
