Synthesis,Crystal Structure,Thermal Stability Property and Antibactericidal Activity of Binuclear Lead Complex of O,O′-Di(p-tert-butylphenyl)dithiophosphate

A new binuclear lead complex [Pb2(S2P(OR1)2)2(μ-S2P(OR1)2)2](R1 is p-tert-butylphenyl group) was synthesized and characterized by elemental analysis,IR,UV-Vis,TG-DSC,and single crystal X-ray diffraction analysis.The crystal structure study shows that the title complex is dinuclear structure which form an chair conformation of eight-membered ring [Pb2S4P2],and the lead atom is in a distorted ψ-pentagonal bipyramidal coordination environment Pb(S5ArE) by means of the weak π coordination from an aryl group of the bridging(R1O)2PS2-ligand to lead atom and a lone pair of stereochemically active electrons originating from the lead atom.The antibacterial activities of the raw material(R1O)2PS2NH2Et2 and complex were studied against E.Coli,B.Subtilis,and S.Aureus.The bioactivity test shows that both the raw material and complex can inhibit three kinds of bacteria,and the complex has higher antibacterial activity being compared with the raw material against E.Coli and B.Subtilis.CCDC: 870009.
