Different coordination modes of neutral and deprotonated ZC(S)N(H)R ligands (Z = PPh2, R = Ph, Me; Z = NMe2, R = Ph) in molybdenum and tungsten complexes. X-ray structure analysis of [Mo(CO)2[Ph2PC(S)NMe][μ-Ph2PC(S)NMe]] 2·CH2Cl2

The hetero allyl derivatives Ph2PC(S)N(H)R (R = Ph, Me) react with Mo(CO)4Cl2 and M(CO)3(PPh3)2Cl2 (M = Mo, W) to give two isomers of the formula M(CO)2[Ph2PC(S)N(H)R]2Cl2, e.g. one ionic complex with two P,S-bidentate ligands and one neutral complex with one P-monodentate and one P,S-bidentate ligand. For R = Me this isomeric mixture reacts with NH4+PF6- to give the ionic [M(CO)2Cl[Ph2PC(S)N(H)Me]2]+PF 6- wherein both ligands are coordinated through P and S. The dichloride complexes react with Et3N, giving monomeric complexes M(CO)2[Ph2PC(S)NR]2 (M = Mo, W; R = Ph, Me). An X-ray structure analysis of the crystalline compound Mo(CO)2[Ph2PC(S)NMe2]2 (a = 18.958 (8) ?, b = 19.542 (8) ?, c = 18.879 (8) ?, β = 90.84 (5)°, space group C2/c, and Z = 4) revealed the compound to be dimeric [Mo(CO)2[Ph2PC(S)NMe][μ-Ph2PC(S)NMe]] 2 in which one ligand acts as a bridge between the two Mo atoms and the other ligand coordinates in a bidentate manner through P and S. The thiourea derivative Me2NC(S)N(H)Ph reacts with Mo(CO)4Cl2 or M(CO)3(PPh3)2Cl2 (M = Mo, W) and Et3N to give complexes of the type M(CO)2(L)[Me2NC(S)NPh]2 (L = CO and PPh3, respectively). All compounds were characterized by means of elemental analyses, infrared spectroscopy, and 1H and 31P{H} NMR spectroscopy.
