[2-((R)-{2-[(S)-1-Benzylpyrrolidin-2-yl-carbonylazanidyl]phenyl}(phenyl)methylideneamino)-4-hydroxybutanoato-kappa(4)N,N ',N '',O(1)]nickel(II) toluene disolvate

Abstract

The central Ni atom in the title compound, [Ni(C29H 29N3O4)]·2C7H8, is coordinated in a distorted squareplanar environment by three N atoms [Ni - N = 1.942 (3), 1.843 (3) and 1.853 (3) Å] and one O atom [1.868 (3) Å] of the tetradentate ligand. The conformation of the hydroxybutanoate side chain is controlled by an intermolecular hydrogen bond.
