Two new oximate-bridged square-planar dinuclear nickel(II) complexes

M. Bera and B. C. Noll

Abstract: The synthesis and characterization of two new dinuclear nickel(II) complexes, namely bis­{[mu]-3-[2-(dimethyl­amino)­ethyl­imino]butan-2-one oximato}dinickel(II) bis­(perchlorate) acetonitrile solvate, [Ni2(C8H16N3O)2](ClO4)2·CH3CN, (I), and bis­{[mu]-3-[2-(dimethyl­amino)ethyl­imino]-3-phenyl­propan-2-one oximato}dinickel(II) bis­(perchlorate), [Ni2(C13H18N3O)2](ClO4)2, (II), are reported. Single-crystal X-ray analyses of the complexes reveal that the nickel(II) ions are in square-planar N3O environments and form six-membered (NiNO)2 metallacycles. The cation in (II) possesses crystallographically imposed inversion symmetry.

Formula: [Ni2(C8H16N3O)2](ClO4)2·C2H3N and [Ni2(C13H18N3O)2](ClO4)2
