Alkali scandium arsenates. I. The framework structures of KSc(HAsO₄)₂ and RbScAs₂O₇

K. Schwendtner and U. Kolitsch

Synopsis: KSc(HAsO₄)₂ and RbScAs₂O₇ are both characterized by three-dimensional octahedral-tetrahedral frameworks, with intersecting tunnels hosting the alkali atoms. KSc(HAsO₄)₂ represents a new structure type, while RbScAs₂O₇ is the first reported diarsenate isotypic with KAlP₂O₇.
