Spoilt for choice : a silane, dihydrogen, borane, or hydridoborate complex? The silyl boryl hydride complex [Cp*Rh(H 2 )(Et 3 Si)(Bpin)] (Bpin=(pinacolato)boryl) could adopt any of these structures, but it appears to contain stronger BH bonding than SiH or HH bonding and undergoes elimination of pinacolborane faster than of silane or hydrogen (see scheme). The bonding situation is studied by experimental and theoretical methods.
