Di-?-bromido-bis-[bromido(di-2-pyridylmethane-diol-?N,N')copper(II)] dihydrate.

ABSTRACT: The centrosymmetric title complex, [Cu(2)Br(4)(C(11)H(10)N(2)O(2))(2)]·2H(2)O, was one of three complexes isolated by slow evaporation of an acetonitrile reaction mixture of CuBr(2) with di-2-pyridyl ketone (1:1 molar ratio). The title complex contains a 1:1 metal-to-ligand ratio of copper(II) with the hydrated form of the ligand di-2-pyridylmethane-diol. The copper centers are bridged by bromide donors, leading to a Cu-Cu distance of 4.090?(6)?Å. The crystals form as non-merohedral twins with two components related by a 180° rotation around the normal to [100]; the selected sample had a twin ratio of 0.63:0.37.
