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) Å, α = 97.188(3), β = 96.394(4), γ = 111.430(4)°, V = 1298.73(10) Å³, Z = 2, D_c = 1.409 g/cm³, μ(MoKα) = 1.074 mm^-1, F(000) = 572, S = 1.078, R = 0.0381 and wR = 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 Cu^II/Cu^I couple.
