Triple-Decker Sandwich Complexes with cyclo-P6 as Middle DeckThe cothermolysis of white phosphorus (P4) and [(η5-C5Me5)2-(CO)nW2] (1; n = 4, 6) as well as [(η5-C5Me4R)V(CO)4] (3) affords the triple-decker sandwich complexes [{η5-C5Me5)W}2(μ,η6-P6)] (2) and [{η5-C5Me4R)V}2(μ,η6-P6)] (4a, R = CH3; 4b, R = C2H5). 2 and 4b have been characterized by X-ray structure analyses, 2 and 4a as well as A and B by electrochemical, ESR, and electronic spectroscopy measurements. An empirical valence-electron rule for triple-decker complexes is derived.
Notes:
Die Cothermolyse von weißem Phosphor (P4) und [(η5-C5Me5)2-(CO)nW2] (1; n = 4, 6) sowie [(η5-C5Me4R)V(CO)4] (3) ergibt die Tripeldecker-Sandwichkomplexe [{η5-C5Me5)W}2(μ,η6-P6)] (2) und [{η5-C5Me4R)V}2(μ,η6-P6)] (4a, R = CH3; 4b, R = C2H5). 2 und 4b wurden kristallstrukturanalytisch, 2 und 4a sowie A und B elektrochemisch, ESR- und elektronenspektroskopisch charakterisiert. Es wird eine empirische Valenzelektronenregel für Tripeldecker-Komplexe abgeleitet.
