The　title　complex　NiL(py)3,　where　H2L　=　N-salicylaldehyde-N′-phenoxyacetyl　hydrazine,　was　prepared　and　characterized　by　X-ray　diffraction.　The　single　crystal　of　the　title　compound,　Ni(C15H12N2O3)(C5H　5N)3,　is　of　monoclinic,　space　group　P21/c　with　a　=　11.900(1),　b　=　9.6855(7),　c　=　23.658(2)　Å,　β　=　92.357(2)°,　V　=　2724.5(4)　Å3,　Z　=　4,　F(000)　=　1176,　Dc　=　1.376　g/cm3,　μ　=　0.753　mm-1,　R　=　0.0332　and　wR　=　0.0820.　The　coordination　polyhedron　around　the　nickel　atom　is　an　elongated　octahedron.　The　basal　plane　consists　of　one　phenol　oxygen,　one　amine　carbonyl　oxygen　and　one　hydrazine　nitrogen　atoms　from　the　ligand　L　and　one　nitrogen　atom　from　one　coordinated　pyridine　ligand,　while　the　axial　sites　are　occupied　by　two　nitrogen　atoms　of　two　coordinated　pyridine　ligands.
