Two New Cluster Ions, Ga[GaH(3)](4)(5-) with a Neopentane Structure in Rb(8)Ga(5)H(15) and [GaH(2)](n)(n-) with a Polyethylene Structure in Rb(n)(GaH(2))(n), Represent a New Class of Compounds with Direct Ga-Ga Bonds Mimicking Common Hydrocarbons

The first examples of a new class of gallium hydride clusters with direct Ga-Ga bonds and common hydrocarbon structures are reported. Neutron powder diffraction was used to find a Ga[GaH(3)](4)(5-) cluster ion with a neopentane structure in a novel cubic structure type of Rb(8)Ga(5)H(15). Another cluster ion with a polyethylene structure, [GaH(2)](n)(n-), was found in a second novel (RbGaH(2))(n) hydride. These hydrocarbon-like clusters in gallium hydride materials have significant implications for the discovery of hydrides for hydrogen storage as well as for interesting electronic properties.
