Synthesis and characterisation of [Ru4{µ4-PC(CO)But}2(µ-CO)(CO)10] and [FeRu3{µ4-PC(CO)But}2(µ-CO)(CO)10]: cluster expansion by addition of metal carbonyl fragments to nido-clusters
Abstract
The two new µ4-phosphinidene cluster compounds [Ru4{µ4-PC(CO)But}2(µ-CO)(CO)10] and [FeRu3{µ4-PC(CO)But}2(µ-CO)(CO)10] are prepared by addition of the isolobal 12-valence electron fragments Ru(CO)2 and Fe(CO)2 to the nido-cluster [Ru3{µ3-PC(CO)But}2(CO)9].
