Computational study of CdII complexes including bidentate phosphorus ylides

this work, [Cd(L) Nx2 ] complexes (n = 1, 2; X Cl,Br, I; L = PPh2CH 2PPh 2CHCOCH 3) have been )modeled and studied by density functional theory. The title ylide can be coordinated to the metal ion as a bidentate and monodentate ligand. For the reaction between the CdCl2 and ligand we can consider two possible products, , 1+1 or 1+2.The result show that P, O -coordinated isomer for 1+1 product and O, O -coordinated isomer for 1+2 product are more stable than the other isomers. Other are more stable than the other isomers. Other are more stable than the other isomers. Other are more stable than the other isomers. Other are more stable than the other isomers. Other are more stable than the other isomers. Other properties as the calculated length bond and angle bond, hardness, energy gap also reported.
