A new mononuclear copper(II) complex [CuL(Phen)]’NO3 (L = 2-{2-[(3,5-dibro- mosalicylidene)amino]ethyl}-1H-1,3-benzimidazole, Phen = 1,10-phenanthroline) has been synthe- sized and its crystal structure was determined by X-ray diffraction method. It crystallizes in mono- clinic, space group C2/c with a = 24.966(7), b = 15.673(4), c = 16.600(5) ’, β = 123.981(4)o, C28H20Br2CuN6O4, Mr = 727.86, V = 5386(2) ’3, Z = 8, Dc = 1.795 g/cm3, μ(MoKα) = 3.826 mm-1, F(000) = 2888, the final R = 0.0508 and wR = 0.1024 for 5440 independent reflections with Rint = 0.1134. The title compound is composed of [CuL(Phen)]+ cation and NO3- anion. The coordination geometry around copper atom is a highly distorted trigonal bipyramid consisting of one benzi- midazole nitrogen atom, one phenolato oxygen atom and one phenanthroline nitrogen atom on the equatorial plane together with one imine nitrogen atom and one phenanthroline nitrogen atom occupying the axial positions. The hydrogen bonding and π-π stacking interactions link the copper complex molecules into a 3-D supramolecular structure.
