K₂NbAlO₂[(As,Nb)O₄]₂, isostructural with KTiOPO₄

T. Nakagawa, T. Matsumoto, V. I. Chani and T. Fukuda

The title compound, potassium niobium aluminium arsenate (KNAA), is isostructural with KTiOPO₄ (KTP). In KNAA, the site corresponding to the Ti1 sites of KTP is occupied mostly by Nb atoms, the Ti2 site is occupied predominantly by Al atoms, and the As1 and As2 tetrahedral sites are occupied mostly by As atoms.
