Abstract
Four of the coordination compounds of the general formula, [M(DPPP)(APY)(H2O) Cl2].xH2O, where M = Ni(II), Cu(II), Mn(II), and Fe(II) and x = 0, 1, or 2 molecules of H2O, DPPP = 1,3-bis(diphenylphosphino)propane, and APY = 2-aminopyridine, have been prepared and characterized. The structure of the complexes has been confirmed by elemental analysis, FT-IR, and UV-Vis spectral data. Thermal analysis (thermogravimetry, derivative thermogravimetry, and differential thermal studies) has been used to study the thermal decomposition stages. Biological activity of all synthesized complexes was tested against five bacterial strains and three fungal strains. Bacteria and fungi strains are common contaminants of the environment in Saudi Arabia, some of which are frequently reported from contaminated water, soil, and food.
Highlights
Coordination compounds have been known since the beginning of modern chemistry; coordination compounds are so common that their structures and reactions are described as in many ways. e atom within a ligand is bonded to the central metal atom
It is degraded in air to phosphine oxide and slightly air-sensitive. It is classified as a diphosphine ligand in coordination chemistry and homogeneous catalysis [1,2,3]
E mixed use of metal complexes containing diphosphines and other ligands, which consist of N or S atoms have been intensively inspected during the past years because of their possibility applications in the fields of light emitting devices, biological activity, and catalysis [4,5,6,7,8]
Summary
Coordination compounds have been known since the beginning of modern chemistry; coordination compounds are so common that their structures and reactions are described as in many ways. e atom within a ligand is bonded to the central metal atom. In hydrometallurgy, the coordination chemistry of the metals participate plays a large role in their solubility and reactivity, as the ore is refined into a precious transition elements. Diphosphine ligands, such as 1,3-bis(diphenylphosphino) propane, are organophosphorus compounds, and these compounds are white solids that are soluble in organic solvents. It is degraded in air to phosphine oxide and slightly air-sensitive It is classified as a diphosphine ligand in coordination chemistry and homogeneous catalysis [1,2,3].
