Synthesis, characterization and crystal structure of metal complex from amino acid Schiff base of PMNBP

A kind of Schiff base derived from 1-phenyl-3-methyl-4( p-nitrobenzoyl ) -5-pyrazolone ( PMNBP ) with L-phenylalanine methyl ester and its metal ( Ni 2+, Co 2+ ) complexes were synthesized.IR was performed. The crystal structures were measured through X-ray diffraction, and the sixcoordinate isomorphism of the two complexes were determined.
