Tetraphenylborate complexes of rhodium(I)

Abstract

Addition of B(C 6H 5) 4 − as precipitating counteranion to cationic four-coordinate rhodium(I) complexes with nitrogen donor ligands of the type [(NBD)- RhL 2] + results in a competition between coordination by the tetraphenylborate group (via π-interaction of an arene ring) and the nitrogen donor ligands. The stoichiometry of the precipitated complexes depends on the nature of these ligands.
