Abstract
The structural characterization of the osmahexaborane 2-carbonyl-2,2-bis(tr iphenylphosphine)-nido-2-osmahexabor- ane(9), [Os(B5H9)(C18H15P)(2) (CO)], (I), a metallaborane analogue of B6H10, confirms the structure proposed fro m NMR spectroscopy. The structure of the osmadecaborane 6-carbonyl-6,6-bis( triphenylphosphine)-nido-6-osmadecabor- ane(13), [Os(B9H13)(C18H15P)(2) (CO )], (IV), is similarly confirmed. The short basal B-B distance of 1.652 (8) Angstrom in (I), not bridged by an H atom, mirrors that in the parent hexa borane(10) [1.626 (4) Angstrom].
