Deskripsi
The asymmetric unit of the title trinuclear NiII compound, [Ni3(C11H11N2O3)(C5H5N)4], contains two independent molecules which are located on individual inversion centres. The central Ni atom, located on an inversion centre, is coordinated by two pyridine N atoms and is further N,O-chelated by two N-(2-methylpropanoyl)salicyloylhydrazidate anions in an elongated octahedral coordination geometry. The terminal Ni atom is coordinated by a pyridine ligand and is further N,N′,O-chelated by an N-(2-methylpropanoyl)salicyloylhydrazidate anion in a distorted square-planar coordination geometry. Weak intramolecular C—H...O hydrogen bonding is observed in the structure.
