Beryllium Compounds
In the mid-1960s, considerable interest in beryllium hydride was generated by its potential use with ammonium perchlorate oxidizer in solid propellants for rockets. Beryllium hydride, BeH2 , was prepared by action of ethereal lithium-aluminum hydride with beryllium chloride. A white powder resulted from which the complete removal of ether was difficult. The hydride is not stable above 125 °C (255 °F), decomposing into beryllium and hydrogen.
Beryllium hydride is a three-dimensional polymer, considerably ionic in character and containing Be2+ and H- ions. Alternatively, it may be considered to be an electron-deficient molecule, similar to beryllium chloride and the beryllium alkyls, with hydrogen bridges between the two beryllium atoms (BeH2Be).
