Hydrogen Bonds Involving Metal Centers

N. Raos
G. Pavlović

Sažetak

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 (η5-C₅R₅)ML₂, where M stays for Co, Ir or Rh, R for H or CH₃, and L for CO, PMe₃ or C₂H₄. 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.
