Graphical 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 δ-agostic interaction of a η2-BH bond involving a trivalent boron atom or a dihydroborate ligation.

- 20True σ-complexes can be defined as a complex in which the σ-ligand is only coordinated to the metal center through the σ-bond, whereas in an agostic species, the ligand is bound to the metal by an additional group (either L or X). We define true σ-boranes as complexes containing neutral HBR2 ligands.

- 28The shortest bond (1.313 Å) is observed trans to the strongest ligand, the hydride. The σ(BH) to σ*(RuH) 2nd-order perturbation energy amounts to 288 kJ mol−1, a value significantly lower than the σ(BH) to σ*(RuP) 2nd-order perturbation energy of 442.7 kJ mol−1 for the donation of the BH bond trans to the phosphine. As a matter of fact, the larger donation from the BH bond trans to P explains the longer bond observed for BH (1.366 Å).
