Question

help with the following ligand electron counting question

Question 5. You find a compound on the chemical shelf labeled “Re(PMe3)s”. Without adding or removing ligands or introducing charges, demonstrate that this species can satisfy the 18-electron rule by drawing a reasonable structure and counting the electrons about the metal center. PMe = 2ě each Pines 2x5=10e Reco) = d7 P Me - Renump Mez I Mes PMez in under go le reduction to Stabilize?

Answer 1

Dear Student, Reco) - dos = 7 electron :P Mez = 2 electron Structure will be Mez Me Total é count me p - Re = 7+2x5 I me - 7+ 10 = 17e So this species can not without introducing a The species which satisfy satisfy the 10 e sule extra regative charge the lo é sule will be mez mez Mop - Re my parent with Regards,
