(Acetato-κO)bis-(2,2'-bipyridyl-κN,N')copper(II)-ethyl sulfate-methyl sulfate (1/0.5/0.5).

In the title complex, [Cu(C(2)H(3)O(2))(C(10)H(8)N(2))(2)](CH(3)CH(2)OSO(3))(0.5)(CH(3)OSO(3))(0.5), the Cu(II) ion is bis-chelated by two 2,2'-bipyridine lignds and coordinated by an O atom of an acetate ligand in a CuN(4)O disorted square-pyramidal environment. In the structure, equal amounts of methyl sulfate and ethyl sulfate anions are disordered on the same crystallographic sites. The crystal structure is stabilized by weak inter-molecular C-H⋯O inter-actions.
