| Summary: | Hydrogen bonds involving metal center as a hydrogen donor or hydrogen acceptor are only a specific type of metal-hydrogen interactions; it is therefore not easy to differentiate hydrogen bond from other metal-hydrogen interactions, especially agostic ones. The first part of the review is therefore devoted to the results of structural chemistry and molecular spectroscopy (NMR, IR), as a tool for differentiating hydrogen bondings from other hydrogen interactions. The classical examples of Pt···H-N, Pt···H-O, Pt···H-C, and Pd···H-N hydrogen bonds were discussed as well as hydrogen bonds involving half-sandwich complexes (η<sup>5</sup>-C<sub>5</sub>R<sub>5</sub>)ML<sub>2</sub>, where M stays for Co, Ir or Rh, R for H or CH<sub>3</sub>, and L for CO, PMe<sub>3</sub> or C<sub>2</sub>H<sub>4</sub>.. The paper deals also with metal donating (M-H···A) and bifurcated hydrogen bonds. The hydrogen interactions in complexes of other heavy metals (Ni, Cu, Ag, Os) were also briefly discussed. |
