摘要
Using4-[(1-naphthylamino)phenylmethylene]-5-methyl-2-phenyl-2H-pyrazol-3(4H)one(L),its Co (Ⅱ) complex was synthesized and characterized by IR and UV in which the ligand as a-1valence bidentate with Co (Ⅱ) form2∶1complex.X-ray structure analysis indicates that the Co (Ⅱ) ion is coordinated with oxygen atoms of pyrazolinon,nitrogen atoms of imine and oxygen atoms of DMF molecules to form a distorted six-coordination octahedron.π - π reciprocity and aromatic stack interaction are observed.There are no intra-and inter-hydrogen bond in the crys-tal and the complexes are held together by electronic and Van der Waals forces.
