“…An interaction between a terminal CO ligand and the bridging hydride ligand (2.556 Å) is also present in crystalline (μ-H)Os 3 (CO) 9 (MeCCHCMe) (DEVPEZ). As observed above for BOBTAN10 and BOXQUG, two different type of interactions are present in crystalline (μ-H)Os 3 (CO) 10 (CNPr)(OCOCF 3 ) (HANTIZ) (see Table ). The first link is between the unique H(hydride) and a CO ligand (M−H- - -O distance 2.637 Å), while the second, shorter, interaction is formed between an H(CH) of the CNPr ligand and an oxygen of the carboxylic ligand of a second molecule (2.426 Å).…”

M-H---O hydrogen-bonding interactions in crystalline organometallic complexes and clusters of the transition metals have been investigated. Molecular and crystal structures determined by neutron and/or X-ray diffraction data have been retrieved from the Cambridge Structural Database. In a number of cases there is clear manifestation of M-H---O hydrogen bonding involving metal-bound H("hydride") atom(s) and oxygen atoms mainly belonging to CO groups. When the H-ligands are electronically suited to being hydrogenbonding donors, the absence of M-H---O interactions is due to the steric congestion around the coordination sites of the H-ligands. Individual crystal structures have been examined in detail. It is suggested that the M-H---O hydrogen bond is an example of a soft intermolecular interaction and is comparable in strength to C-H---O hydrogen bonds.
