摘要：

Calcium magnesium nickel tetrahydride, CaMgNiH4, and its deuteride were prepared by sintering ternary metal alloy powders at 450-460-degrees-C under 100-130 bar hydrogen (deuterium) pressure, and characterized by X-ray and neutron powder diffraction. The compound crystallizes with a cubic structure (space group P2(1)3, a = 6.7414(4) angstrom (hydride) and 6.7301(4) angstrom (deuteride) at 298 K) that contains [NiD4]4- complex ions in which two types of deuterium atoms surround nickel in an ordered, nearly regular tetrahedral configuration with bond distances [Ni-D1] = 1.597(9) and [Ni-3 X D2] = 1.602(8) angstrom, and bond angles in the range [D-Ni-D] = 107.6(5)-degrees-111.3(5)-degrees. The thermal stability as measured from pressure-composition isotherms on the hydride is DELTA-H(des) = - 129(3) kJ (mol H-2)-1.
