Abstract	Reaction of [{RhCl(CO)2}2] with a phosphine/thioether/borane ligand (TXPB) gave [Rh(-Cl)(CO)(TXPB)], a rare example of a complex containing a M-Cl-BR3 bridging interaction. Reaction of 1 with K[CpFe(CO)2] gave [(TXPB)Rh(-CO)2Fe(CO)Cp], which contains an unprecedented 3-interaction between rhodium and the B-Cipso-Cortho unit of a triarylborane. DFT calculations suggest a bonding description intermediate between that expected for an isolated borane/alkene complex and a fully delocalized allyl-like complex.
