Crystal and Electronic Structures of Li-N-H and Related Hydrogen Storage Materials
The crystal structures of LiNH 2, Li 2NH, and Li 4BN 3H 10 were reinvestigated using powder neutron diffraction with high sensitivity. The lattice parameters and atomic positions were determined using Rietveld refinement. It is found that the refined atomic positions of H and the bond distances of N-H are significantly different from previous reports. The electronic structures were calculated according to the revised structural data. The calculated density of states and charge density distribution show strong ionic interactions between the Li cations and the covalently bonded [NH 2] - and [BH 4] -1 anions, in accord with previous studies. © 2007 Materials Research Society.
