N2  - Nickel(11) complexes of the type NiL2Bn have been prepared where L = 2-hydroxy-5-methylacetophenone, 2-hydroxy-5-methylbenzophenone, or 5-chloro-2-hydroxybenzophenone; B = H2O or 4-methylpyridine; n = 2 or 0. The properties of these compounds closely resemble those of the unsubstituted compounds described in Part I. Molecular weights of the anhydrous compounds NiL, indicate a monomer-polymer equilibrium in non-donor solvents, the solute being almost wholly monomeric at concentrations below 10-2M. Equilibrium studies in 2.5M 10-8M solution show that NiL2 reacts with 4-methylpyridine in two stages with a five-coordinate intermediate NiL2B, analogous to corresponding copper(11) complexes. The properties of the monomeric form of NiL, are consistent with a high-spin square-planar structure.
