Bis(?(2)-2-chloro-benzoato-?O:O')bis-[(2-chloro-benzoato-?O)(1,10-phenanthroline-?N:N')copper(II)] dihydrate.

ABSTRACT: In the title compound, [Cu(2)(C(7)H(4)ClO(2))(4)(C(12)H(8)N(2))(2)]·2H(2)O, the two crystallographically independent dinuclear complex mol-ecules, A and B, have different Cu?Cu separations, viz. 3.286?(1)?Å in A and 3.451?(1)?Å in B. Both independent mol-ecules reside on inversion centres, so the asymmetric unit contains a half-mol-ecule each of A and B and two water mol-ecules. Each Cu atom has a square-pyramidal environment, being coordinated by two O atoms from two bridging 2-chloro-benzoate ligands, one O atom from a monodentate 2-chloro-benzoate ligand and two N atoms from a 1,10-phenanthroline ligand. The water mol-ecules can also be considered as coordinating ligands, which complete the coordination geometry up to distorted octa-hedral with elongated Cu-O distances, viz. 3.024?(3)?Å in A and 2.917?(3)?Å in B. In the crystal, weak inter-molecular C-H?O inter-actions contribute to the consolidation of the crystal packing.
