摘要：

Li4RuH6, Na4RuH6, and Li4OsH6 have been synthesized. Structure determinations based on X-ray and neutron powder diffraction data revealed the hydrides to have the rhombohedral K4CdCl6 type structure in space group R3-c (167). With a hexagonal setting the triple unit cell dimensions were Li4RuH6: a = 8.1686(29) Å, c = 10.0255(15) Å; Na4RuH6: a = 9.1526(6) Å, c = 11.3778(11) Å; Li4OsH6: a = 8.2468(38) Å, c = 10.1187(36) Å, and Z = 6. The structure can be characterized by isolated MH4-6 (M =Ru, Os) ions located in a cube of alkali metal ions. The low formal oxidation state of the transition metal atom was attributed to the large polarizability of the metal-hydrogen bond. © 1991 Academic Press, Inc.
