Abstract: The new Schiff base bidentate H2L 6-(4-Amino-2-phenyl-2,4-dihydro-pyrazol-3-ylideneamino)-pyrimidine-2,4-diol. Has been synthesized from condensation of 6-Amino-pyrimidine-2,4-diol with 4-Amino-2-phenyl-2,4-dihydro-pyrazol-3-one. Monomeric complexes with the general formula= [M (H2L) Cl2] where M(II) = Co, Ni, Cu, Zn, Cd and Hg are reported. New Schiff base the of structures mode of bonding and overall structure geometry of the complexes were determined through by the 1H-NMR, FT-IR, Mass and UV-Vis, spectral studies, TGA curve, magnetic moment measurements, elemental microanalyses (C. H. N and O. ), chloride containing, Atomic absorption and conductance. These studies revealed tetrahedral geometries for all complexes. Complexes formation studies via molar ratio and continuous variation methods in (N, N’-dimethyl formamide) solution were consistent to those found in the solid complexes with a ratio of (Metal: Ligand ) (1 : 1). A theoretical study was carried out using program Hyper Chem-8 of new compounds that were prepared in this research. It identified the most stable geometric shapes, as well as the total energy, the heat of formation, bonding energy and dipol moment. Study the effect of compounds prepared against different types of bacteria and fungus
