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