Reversible oxidation of [MonW3–n(η5-C5H5)3(CO)6(µ3-P)] (n = 0–3) by sulfur; synthesis and characterisation of [MonW3–n(η5-C5H5)3(CO)6(µ3-PS)] (n = 0–3)
Abstract
The trimetallic tetrahedrane complexes [MonW3–n(η5-C5H5)3(CO)6(µ3-P)] (n = 0–3) are oxidised in carbon disulfide solution by elemental sulfur to the corresponding µ3-PS complexes [MonW3–n(η5-C5H5)3(CO)6(µ3-PS)]; the new complexes lose the sulfur atom upon standing in solution at room temp. to regenerate [MonW3–n(η5-C5H5)(CO)6(µ3-P)]; the X-ray crystal structure of [W3(η5-C5H5)3(CO)6(µ3-PS)] is determined.
