title: Phosphinoborane and sulfidoborohydride as chelating ligands in polyhydride ruthenium complexes: agostic sigma-borane versus dihydroborate coordination.
abstract: A question of coordination mode: Two new borane compounds are prepared. They act as bifunctional ligands as illustrated by their reaction with ruthenium polyhydrides which leads to the formation of two complexes (see scheme) displaying either a delta-agostic interaction of a eta(2)-B-H bond involving a trivalent boron atom or a dihydroborate ligation.
