Synthesis and characterization of [Et4N][M(CO)5SR] and [Et4N]2[M2(CO)8(SR)2] complexes (M = Cr, Mo, W). Ligand substitution reactions and X-ray crystal structure of [Et4N]2[W2(CO)8(SPh)2]

A series of complexes, [Et4N][M(CO)5SR] (M = Cr, Mo, W; R = H, Ph), have been synthesized and characterized by 1H and 13C NMR and IR spectroscopies. Gentle heating causes these complexes to lose a carbonyl ligand, yielding the doubly bridged sulfur dimers M2(CO)8(μ-SR)22-. The X-ray crystal structure of [Et4N]2[W2(CO)8(SPh)2] has been determined. The complex crystallizes in the triclinic space group P1 with unit cell parameters a = 9.8664 (17) A?, b = 9.8566 (22) A?, c = 11.8270 (26) A?, α = 65.790 (16)°, β = 81.710 (16)°, γ = 82.000 (16)°, V = 1034.0 (4) A?3, and Z = 1. Both mono- and dinuclear metal complexes readily react with phosphorus donor ligands to afford the carbon monoxide substituted complexes cis-M(CO)4(P)(SR)- (P = PMe3, P(OMe)3, PPh3). In addition, the dimers react with 1 atm of carbon monoxide to re-form the mononuclear species M(CO)5SR- in quantitative yields. Unsuccessful attempts to insert CO2, COS, or CS2 into the M-SR bond in the M(CO)5SR- derivatives are noted.
