Regularities of intramolecular hydrogen bonding to transition metal atoms have been educed. Three new types of intermolecular hydrogen bonds typical for organometallic compounds have been discovered: to transition metal atom as proton acceptor, to hydride ligand as proton acceptor and of hydride ligand as proton donor; spectroscopic criteria of their formation have been established. Approaches to mechanistic studies of two- and three-step reactions of transition metal and group 13 element hydrides with proton donors have been developed. Formation of unusual hydrogen bonds with hydride ligand or transition metal atom has been shown to determine the proton transfer pathway and the reaction selectivity. Thermodynamic and kinetic parameters of each reaction step have been determined; the experimental and theoretical data about the potential energy profiles of the reaction have been acquired.
