| Abstract The preparation structural identification of some transition metal complexes of new thiazolylazo ligand 2-[ (2-Thiazolyl) azo ]-4-benzyl phenol (TABP = HL) are studied on the basis of their analytical, spectroscopic, magnetic susceptibility and conductance data. The stability constant of prepared complexes have been determined by spectrophotometric method. The stability of complexes follows the sequence; Cu(II) > Co(III) > Ni(II) > Hg(II) > Cd(II) > Zn(II) > Ag(I). The isolated solid complexes are found to have the general formula [ ML2 ].x H2O (M = Ni(II), Cu(II), (x = 1), M = Zn(II), Cd(II), Hg(II), (x = 2) or [ CoL2 ]Cl.H2O and [ AgL(H2O) ]. H2O. Structural information has been taken from spectroscopic, magnetic and molar conductance measurements. The coordination number of all metal ions is found to be six, except of Ag(I) complex was found four, with binding through the phenolate O, azo N and with thiazole N atom. | ||
