ChemInform Abstract
Bonding properties, location and mobility of hydrogen in molybdenum bronzes HxMoO3 with hydrogen contents in the range x = 0.2-2.0 have been studied using 1H NMR solid state techniques. Temp. dependent spectra characteristic of different degrees of intercalation have been observed. Dynamic properties have been derived from measurements of the relaxation rate. There is strong evidence of intralayer hydrogen positions on a quasi-one-dimensional zig-zag line connecting the vertex-sharing oxygen atoms of the MoO6 octahedra; these are first occupied if the degree of intercalation is low.
