The preparation of some new coordination compounds for cobalt (II), nikel (II), and copper (II) with Schiff base ligand derived from 4-Amino antipyrine, sulphadiazine and acetoacetanilide. Ligand (4- APSDA) were prepared and then react with metal salts in ethanol as asolvent in 1 : 1 ratio (metal : ligand). The complexes which have the general formula [MLCI.2H2O] where M = Co(II), Ni(II) and Cu(II). Ligand and its metal complexes were characterized using metal analysis by atomic absorption, infrared spectra, electronic spectra, 1H NMR spectral studies, molar conductance and magnetic moment measurements. The measurements indicated that the ligand coordinate with the metal (II) ion in neutral tridentate manner through the azo methane nitrogen atoms, and oxygen group of the acetoacetanilide, stability constant of complexes were calculated by spectrophotometricaly. All the studies reveal a coordination six for the metals in all the complexes. Octahedral structures were suggested for metal complexes
