The reaction between 2- in refluxing MeOH gives as a bright yellow air-stable compound in low yield.Crystals are triclinic, space group P1/ with a = 948.8(4), b = 1 675.6(6), c = 1 855.0(6) pm, α = 101.48(3), β = 99.55(3), γ = 99.82(3) deg, and Z = 4.An occasional by-product of the reaction is the yellow compound , crystals of which are orthorhombic, space group P212121, with a = 1 267.5(3), b = 1 269.9(3) c = 1 683.4(3)pm, and Z = 4.In each compound the RhB10 cluster is a closed eleven-vertex deltahedron, the hexahapto borane-metal linkage being effected via one Rh-H-B and five Rh-B connectivities.The metal centre is an 18-electron d6 rhodium(III) atom which can be thought to contribute four orbitals to the metallaborane cluster bonding scheme, thus inducing 'isocloso' cluster character.The presence of a bridged metal-hydrogen-boron linkage on the closed polyhedral cluster is also notable.
