A new series of Co(II), Ni(II), Cu(II) and Zn(II) metal complexes of ligand 4-((E)-((6Z,13E,16Z)-14-methyl-6,7-diphenyl-16-(phenyl
amino)-8,15-dihydro-5H- dibenzo[b,h][1,4,7,10]tetraazacylo tridecin-15-yl)diazenyl)-N-(pyrimidin-2-yl)benzene sulfonamide were synthesis,
characterized and structural of Co(II), Ni(II), Cu(II), and Zn(II) complexes with tetra dentate ligand. The new tetra azo methane macro cyclic
ligand derived from sulphadiazine, acetoacetanilide, o-phenylene diamine and benzil with Monomeric complexes with the general formula
[M(L)]Cl2 Where M= Co(II), Ni (II), Cu (II), and Zn(II), are reported. The Structures of new ligand , mode of bonding and over all geometry of the
complexes were determined through FTIR, UV-Vis, and 1HNMR spectral studies, magnetic moment measurement, elemental analysis, metal
content, and molar conductance. These studies revealed square planar geometries for all complexes. Complex formation studies via molar ratio
and continuous variation methods were consisted to those found in the solid complexes with a ratio of ( M:L) as (1:1). Stability constant of
complexes were calculated by spectro photometricaly. spectral data showed that the ligand behaves a tetra dentate molecular with (N4) donor
