摘要：

A new ternary hydride, Ba3Ir2H12, has been synthesized by reacting a mixture of BaH2 and iridium powders in a hydrogen atmosphere. The crystal structure was determined by combining Guinier-Hagg X-ray powder diffraction and neutron diffraction data from a deuterated compound. The structure was refined (space group, P-3m1; a = 5.4865(3) angstrom and c = 8.8459(10) angstrom; Z = 1). The unit cell contains two slightly distorted [IrH6]3- octahedra which form a La2O3-type structure with the three Ba2+ counterions. Two different Ir-H bond lengths were refined with neutron diffraction data from Ba3Ir2D12: 1.60(1) angstrom and 1.77(2) angstrom.
