As part of our study of the structure-properties of the active centre in the superoxide dismutase, the title compound was synthesized and its single crystal structure was determined by X-ray diffraction method. The title compound is orthorhombic, Pnma, a=1.4061(1), b=1.2347(2), c=0.9308(1) nm, V=1.6160 nmZ=4, D_c=1.782g cm~(-3) D_0=1.78g cm~(-3) μ(MoK_α)=17.3cm~(-1) F(000)=884. Structure was determined by direct method using MULTAN-82 and refined by fullmatrix least-squares to a R value of 0.055 using 1344 reflections. The molecule is mirror symmetric with the imidazole ring disordered and the Cu atom located in a tetra nally distorted octahedral enviroment of the coordination type 4+2 with four nitrogen atoms from diethylenetriamine and imidazole in square planar configuration and two oxyzen atoms from perchlorate ions in the axial positions. The reason we prefer to describe the structure in centrosymmetric space group is briefly discussed.
