In molecular BH3 the molecule is planar with bond angles of 120o so the hybridisation of the central boron atom is sp2. In the dimer B2H6 the molecule has two bridging hydrogens. The hybridisation of each boron is approxomately sp3 and each bridge has a 3 centre B-H-B bond formed by the overlap of the sp3 orbtals on the B atoms and the s orbital on the hydrogen.
