“…Barbaras et al 7 synthesized solid CdH 2 in 1951 from the reaction of dimethylcadmium with lithium aluminum hydride in diethyl ether solution, and it was noticed that solid CdH 2 is unstable and rapidly decomposes into Cd atoms and molecular hydrogen above −20°C. It was reported recently that the reduction of aqueous Cd͑II͒ with sodium tetrahydroborate ͑NaBH 4 ͒ leads to formation of both atomic and molecular cadmium species.…”

The vibration-rotation emission spectra of CdH2 and CdD2 molecules have been recorded at high resolution using a Fourier-transform spectrometer. The molecules were generated in a furnace-discharge emission source by reaction of cadmium vapor with molecular hydrogen or deuterium. The fundamental bands for the antisymmetric stretching mode (upsilon3) of CdH2 and CdD2 were detected at about 1771.5 and 1278.3 cm(-1), respectively. In addition, the 002(sigma(g)+)-001(sigma(u)+) and 01 l(pi(g))-010(pi(u)) hot bands were observed for CdH2. Spectroscopic constants were determined for each of the 12 observed isotopologs: 110CdH2, 111CdH2, 112CdH2, 113CdH2, 114CdH2, 116CdH2, 1l0CdD2, 111CdD2, 112CdD2, 113CdD2, 114CdD2, and 116CdD2. The average Cd-H and Cd-D bond distances (r0) were determined to be 1.683028(10) and 1.679161(16) angstroms, respectively.

“…It has been reported 38 that zinc hydride decomposes to the elements slowly at temperatures as high as 90°C; in another study 28 it was found that this hydride decomposes very slowly at 25°C and that it can be maintained at 50°C for short intervals without color change. 12-3 in connection with discussion of the boron hydride.…”

“…That beryllium forms a covalent hydride should not be surprising since beryllium compounds are generally of a covalent nature, certainly more so than comparable compounds of the heavier alkaline-earth metals. Barbaras 28 reported that it decomposes readily at 125°C, but it has also been reported to decompose only slowly in the temperature range 190° to 200°C 29 and to be stable to temperatures approaching 240°C. From the position of these metal atoms in the periodic table and from their relative stabilities, however, it is clear that these hydrides act as transitions between the covalent hydrides of the main group metals and the nonstoichiometric hydrides of most transition metals.…”

A three-dimensional potential energy surface of the electronic ground state of ZnH(2) (X1 Sigma(g)+) molecule is constructed from more than 7500 ab initio points calculated at the internally contracted multireference configuration interaction with the Davidson correction (icMRCI+Q) level employing large basis sets. The calculated relative energies of various dissociation reactions are in good agreement with the previous theoretical/experimental values. Low-lying vibrational energy levels of ZnH(2), ZnD(2), and HZnD are calculated on the three-dimensional potential energy surface using the Lanczos algorithm, and found to be in good agreement with the available experimental band origins and the previous theoretical values.
