    • Because of the extremely small size (by neutron diffraction standards) of the crystal, we found it necessary to collect data very slowly (approximately 150 reflections per day), and the data set was quite weak. Consequently, the agreement factor is somewhat higher than normally expected. Distances and angles quoted in this report are based on the refinement with all data. A complete set of supplementary tables for this structure analysis, including atomic coordinates, interatomic distances and angles, has been deposited with the Cambridge Crystallographic Data Centre (UK) as CCDC-100105.

    • In the original x-ray work (5, 6), it was predicted that the first H atom would be found in the unique cavity bridged by one CO ligand [Rh(1,3,4,5,13)], and the second H atom in one of the cavities bridged by two CO groups [Rh(8,9,10,12,13)].

    • In our neutron analysis, the eight surface Rh-Rh distances of the two occupied cavities, Rh(1,3,4,5) and Rh(8,9,10,12), average to 2.78(1) Å, whereas the 16 surface Rh-Rh distances of the four unoccupied cavities average to 2.75(1) Å. This represents a 1% expansion in the dimensions of filled holes relative to empty holes and is consistent with (but smaller than) the 2 to 3% expansion deduced from earlier x-ray work (6). Studies on the binary Rh-H system also support an increase in metal-metal distance upon occupation of a cavity by H, with expansions typically in the 5% range [see S. Wilke, D. Hennig, R. Löber, Phys. Rev. B 50, 2548 (1994)].
