Abstract
Electrically conducting vanadium arsenate or vanadium phosphate materials are described. The materials include a vanadium arsenate or vanadium phosphate framework structure about organic template and water molecules which may be removed to leave a microporous structure. The three-dimensional vanadium framework may provide electronic conductivity, while the extra-framework constituents may provide ionic conductivity.
