γ = 80.987(5)° and Z = 2. The crystal structure has indicated that the complex has been slightly distorted octahedral geometry and is chelated by the deprotonated N(3) pyrimidine ring and by the carboxylate oxygen atom of the orotate ligand. One nicotinamide molecule is also coordinated to the metal ion by the N atom of the pyridine ring. The crystal structure consists of discrete monomeric units of
