Аннотация:The interactions between the synthesized salt [(eta5-C5Me5)2OsH]+PF6- (1) and N or O bases were studied by IR spectroscopy. Hydrogen-bond formation of the type [OsH]+ . . . B occurs prior to proton transfer if phosphoryl compounds (Ph3PO, Fc3PO, (Me2N)3PO) are used as bases. In the last case is revealed the equilibrium between such a complex and the product of deprotonation of 1 in solution. There is no evidence for hydrogen-bond formation if 1 is deprotonated by the N bases (Et3N, Py).
