Crystal Structure of Bis(μ-chloro)-bis[chloro (N,N,N'-trisbenzylethylenediamine)copper(Ⅱ)]

The crystal structure of the title complex, Cu(C23H26N2)Cl2]2·2CH2Cl2, has been determined by singlecrystal, X-ray diffraction techniques. The compound crystallizes as dark-green prisms in space group P21/c of the monoclinic system, with Z=4 and unit cell dimensions a=1.7109(7) nm, b=2.395 2(11) nm, c=1.348 9(6) nm and β=110.651(8)°. The complex consists of two similar but crystallographically independent dimers, of which Cu(Ⅱ)centers display five-coordinated trigonal-bipyramidal geometry with Cu-Cu separations in two centrosymmetric dimers are 0.345 1 and 0.347 8 nm, respectively, and in each dimer the two copper centers share a common edge formed by two bridging chloride ions, each being equatorial. Solvent molecules of CH2Cl2 are packed together in the crystal lattice. CCDC: 253299.
