A novel mononuclear copper(Ⅱ) complex [Cu(bbmc)Cl2]·DMF,where bbmc is 1,1-bis(1H-benzoimidazol-2-ylmethyl)cyclohexane,was synthesized and characterized by X-ray single-crystal structure analysis.The complex crystallizes in triclinic,space group P1 with a = 9.1088(5),b = 11.0075(4),c = 14.2326(6) ?,α = 97.188(3),β = 96.394(4),γ = 111.430(4)°,V = 1298.73(10) ?3,Z = 2,Dc = 1.409 g/cm3,μ(Mo Kα) = 1.074 mm-1,F(000) = 572,S = 1.078,R = 0.0381 and w R = 0.0876 for 5593 observed reflections with I > 2σ(I).The central Cu(Ⅱ) ion adopts a distorted tetrahedral geometry coordinated by two nitrogen atoms of the ligand and two chloride ions.The complex showed its thermal decomposition temperature up to 226 ℃ and exhibited an irreversible one-electron transfer process involving CuⅡ/CuI couple.
