This paper reports the synthesis and structure of the imidazolate-bridged dicopper (Ⅱ) complex with tetraaza macrocycles [μ-C3H5N5-Cu2(C10H24N4)2]Br(ClO4)2•C2H5OH (C10H24N4=1,7-dimethyl-1,4,7,10,-tetraazacyclododecane). The crystal structure of the complex has been determined by X-ray single crystal diffraction method. The complex crystallizes in the monoclinic space group P21 /c with a=8.698(3), b=25.713(7), c=18.075(6)Å, β=102.66(3), V=3944(3)A3, Z=4. In the [μ-C3H5N5-Cu2(C10H24N4)2]3+ complex ion the two fivecoordinated copper(Ⅱ) ions are in square pyramid environment, in which the four nitrogen atoms of tetraaza macrocycle form the basal plane and the nitrogen atom from bridged-imidazole occupies the apex of square pyramid. The axial Cu-N bond lengths (average, 2.059 Å) are consistent with the Cu-N bond lengths(average, 2.042 Å) which on the basal plane of the square pyramid.
