Contrasting nonclassical silicon-hydrogen interactions in niobium and tantalum half-sandwich complexes: Si-H center dot center dot center dot M agostic versus M-H center dot center dot center dot Si-Cl interligand hypervalent interactions
Reaction of [CpM(NAr)(PMe3)2] (M = Nb, Ta; Ar = 2,6-C6H3iPr2) with HSiClMe2 gives two remarkably different nonclassical Si···H···M products depending only on the identity of M; [CpTa(NAr)(H)(SiMe2Cl)(PMe3)] possesses an unusual electron-rich M-H···Si interligand hypervalent interaction while [CpNb{η...
