Bis(acetyl-acetonato-?O,O')[copper(II)nickel(II)(0.31/0.69)]: a mixed-metal complex.

ABSTRACT: The title complex, [Cu(0.31)Ni(0.69)(C(5)H(7)O(2))(2)], was isolated from the reaction of bis-(N,N-dimethyamino-ethanol)copper(II) with bis-(acetyl-acetonato)nickel(II), which yielded crystals with mixed sites at the central metal position; the refined copper-nickel occupancy ratio is 0.31?(4):0.69?(4). Two acetyl-acetonate ligands, related by a centre of symmetry, are coordinated to the central metal atom in a square-planar configuration while the methyne C atoms of the acetyl-acetonate ligands, ca 3.02?Å away, are orthogonal to this plane at the metal site.
