REVERSIBLE OXIDATION OF [MONW3-N(ETA(5)-C5H5)(3)(CO)(6)(MU(3)-P)] (N=0-3) BY SULFUR - SYNTHESIS AND CHARACTERIZATION OF [MONW3-N(ETA(5)-C5H5)(3)(CO)(6)(MU(3)-PS)] (N=0-3)

The trimetallic tetrahedrane complexes [MonW3-n(eta(5)-C5H5)(3)(CO)(6) (mu(3)-P)] (n = 0-3) are oxidised in carbon disulfide solution by elem ental sulfur to the corresponding mu(3)-PS complexes [MonW3-n(eta(5)-C 5H5)(3)(CO)(6)(mu(3)-PS)]; the new complexes lose the sulfur atom upon standing in solution at room temp. to regenerate [MonW3-n(eta(5)-C5H5 )(CO)(6)(mu(3)-P)]; the X-ray crystal structure of [W-3(eta(5)-C5H5)(3 )(CO)(6)(mu(3)-PS)] is determined.
