Syntheses of Nickel(II) Dinuclear Complexes with Tetraketone and the Effect of Anions on Coordination Geometries

Three nickel(II) mixed ligand dinuclear complexes were prepared, Ni2(tae)(tmen)2X2·nH2O where tae = tetraketonate; tmen = N-alkylethylenediamine; X− = B(C6H5)4−, ClO4−, or NO3−; n = 0 or 3. Each complex assumes the unique combination of square planar and octahedral coordination geometries in the dinuclear entity.
