In this paper, a new complex [Cu (NIT-1’-MeBzI m) 2Cl2] · 4H2O (NIT-1’-MeBzI m = 2- {2’- [(1’-methyl) Imidazole]]} - 4,4,5,5-tetramethylbenzimidazole-3-oxyl-1-oxyl free radical) was synthesized and its crystal structure was determined.X-ray diffraction analysis showed that the chemical formula of C30H46Cl2Cu N8O8, which belongs to the monoclinic space group C2 / c with unit cell parameters of a = 17.353 5, b = 21.083 6, c = 11.978 3, α = 90 °, β = 111.964 (3) °, γ = 90 °, V = 4064.0 (19) 3, Z = 4 and Dc = 1.277 g / cm3 and the final deviation factor R1 = 0.0786 and wR2 = 0.2213 (I> 2σ ), F (000) = 1636. The center metal Cu (Ⅱ) ions chelate with two free radicals to form a hexa-coordinate deformable octahedron.
