Abstract

"Abstract:Three of the haloorganophosphonates(III)compounds of the chemical formula (CH3)4N[RPCl2X] , where R represents phenyl or propyl groups, and X represents Cl or Br were prepared. These compounds were characterized by I.R , atomic absorption, elemental analysis (CHN) techniques, and conductivity measurments. The biological activity of the prepared compounds was studied, they showed antimicrobial activity against three pathogenic bacteria viz ; Staphylococcus aureus (gram positive), Escherichia coli, and Pesduomonsaeruginosa (gram negative). The effectiveness of these compounds was measured according to inhibition zone and colonies count methods. "
