Beschreibung:
Reaction of CuCl2(H2O)2 with diethylenetriamine (henceforth dien) in a 1:1 ratio has led to the formation of a non-centrosymmetric di-μ-chloro bibridged binuclear CuII species in which a water molecule is coordinated axially to one of the CuII ions. [Cu2Cl2(C4H13N3)2(H2O)] contains dinuclear [(dien)2Cu2Cl2(H2O)]2+ cations and chloride ions. Both CuII ions in the dimer have a primary coordination sphere that is approximately planar, consisting of one dien molecule and one chloride ion. These monomeric units are linked via semicoordinate Cu—Cl bonds to form dinuclear units. One CuII ion has a 4+1 coordination geometry while the second expands to a 4+2 geometry by the incorporation of a water molecule. The dinuclear cation has crystallographic reflection symmetry, the mirror plane containing the central Cu2Cl2 unit and the central N atom of each dien ligand.
