Synthesis and properties of nitrosyl complexes of molybdenum and tungsten containing halide and PMe3 ligands. Crystal and molecular structures of MoCl3(NO)(PMe3)3 and MoCl(NO)(S2CPMe3-S,S′,C)(PMe3) 2

The low-temperature reaction of MCl3(PMe3)3 (M = Mo, W) complexes with NO affords the 18-electron species MCl3-(NO)(PMe3)3 (M = Mo, 1a; M = W, 1b), which display 31P NMR features indicative of well-resolved coupling between the 31P and the 14N nuclei. Sodium amalgam reduction of 1 in the presence of PMe3 gives the M(0) mononitrosyl derivatives MCl-(NO)(PMe3)4 (2a,b). Complex 2a reacts with NaS2CX to afford Mo(S2CX)(NO)(PMe3)3 (X = NMe2, 3; X = OMe, 4). Compounds 2 react with CNCMe3 in a stepwise manner with production of mono- and bis(isocyanide) derivatives, MCl-(NO)(CNCMe3)n(PMe3)4-n (n = 1, 8a,b; n = 2, 9a,b), but the reaction of 2a with CO yields only MoCl(CO)(NO)(PMe3)3 (5). Addition of CS2 to solutions of 2a furnishes MoCl(NO)(S2CPMe3)(PMe3)2 (11), which contains a phosphonium dithiocarboxylate group, Me3P+CS2-, acting formally as a four-electron, η3 S,S′,C pseudo-allylic ligand. The structures of 1a and 11·CHCl3 have been determined by X-ray crystallography. 1a is monoclinic, P21/c, with unit cell constants a = 14.796 (4) A?, b = 11.461 (2) A?, c = 11.461 (2) A?, β= 92.49 (4)°, and D(calcd) = 1.56 g cm-3 for Z = 4. The molybdenum atom is in a seven-coordinate capped-octahedral environment, with the NO ligand capping the P3 face. 11·CHCl3 is also monoclinic, P21/n, with unit cell constants a = 11.536 (7) A?, b = 28.42 (2) A?, c = 9.84 (2) A?, β = 92.42 (4)°, and D(calcd) = 1.56 g cm-3 for Z = 4. The complex contains a zwitterionic ligand, Me3P+CS2-, bonded to molybdenum through the two sulfur atoms and the C atom of the CS2 group. The PCS2 fragment is planar, and the angles around the central carbon atom are close to the ideal 120° value expected for sp2 hybridization.
