Lm. Epstein et al., NOVEL TYPES OF HYDROGEN-BONDS INVOLVING TRANSITION-METAL ATOMS AND PROTON-TRANSFER (XH...M, [MH]-)(...B, [MH]+...A), Journal of molecular structure, 322, 1994, pp. 345-352
The conditions governing the formation of hydrogen bonding involving t
ransition metal atoms of the molecular, ion molecular and ionic types
in low polar media were found. IR and UV-Vis spectral characteristics
of these bonds were determined. Similarities between the spectral prop
erties of hydrogen bonds with a metal atom and with common organic bas
es as well as some particular characteristics of the former were estab
lished. The equilibrium between molecular (OH...M) and ionic (O-...[HM
]-) hydrogen-bonded complexes was investigated.
