摘要

The V4+ (spin 1/2) oxovanadates AV(3)O(7) (A = Ca, Sr) were synthesized and studied by means of single-crystal X-ray diffraction. The room-temperature structures of both compounds are orthorhombic and their respective space groups are Pnma and Pmmn. The previously assumed structure of SrV3O7 has been revised and the temperature dependence of both crystal structures in the temperature ranges 297-100 K and 315-100 K, respectively, is discussed for the first time.
