B-frame supported bimetallics. [(PMe 2ph) 2PtB 9H 11Ru( η6- isoPrC 6H 4Me)] and [(PMe 2ph) 2PtB 9H 9Ru( η6- isoPrC 6H 4Me)]; an interesting pair of electron-deficient nido and closo geometries

Abstract

[7,7-(PMe 2Ph) 2-9-( η 6- iso PrC 6H 4Me)-7,9-PtRuB 9H 11] has a formal closo Wadian cluster-electron count, but a nido geometry, whereas [1-( η 6- iso PrC 6H 4Me)-4,4-(PMe 2Ph) 2-1-4-RuPtB 9H 9], which does have a closo geometry, has a formal sub- closo cluster electron count; both compounds are formed in the reaction between [6-( η 6- iso PrC 6H 4Me)- nido-6 RuB 9H 13], KH and [PtCl 2(PMe 2Ph) 2].
