Weak Hydrogen Bonding in Ethanol and Water Solutions in Liquid Hydrides of Group IV−VI Elements (SiH4, GeH4, PH3, AsH3, H2S, and H2Se). 2. IR Spectroscopy of Hydrogen Bonding in Solutions Containing Water in Hydrides

The results of an IR spectroscoic study of solutions of water in liquid hydrides of the group V and VI elements (PH 3, AsH 3, H 2 S, and H 2 Se) in the temperature range from T b of hydride up to 290 K are presented. The solubility of water in liquid SiH 4 and GeH 4 is lower than the detection limit of infrared spectroscopy. The spectral parameters of the stretching and bending vibration bands of water are measured. The formation of weak hydrogen bonds between the molecules of water and hydrides takes place. To account for the shape of the stretching band of water, 1:2 complexes with hydrides are postulated to be present in these solutions. Their binding energy is estimated. Values of the Gutman donor numbers of the hydrides in the liquid phase are given.
