Crystal structure of (Al,V)(PO), archetype of double cubic ring tetraphosphate.

Yakubovich, O.; Biralo, G.; Dimitrova, O.

The crystal structure of the (Al,V)(PO) solid solution, obtained in the single-crystal form by hydrothermal synthesis in the Al(OH)-VO-NaCl-HPO-HO system, has been solved by X-ray diffraction analysis (Xcalibur-S-CCD diffractometer, R = 0.0257): a = 13.7477(2) Å, sp. gr. I $\bar 4$3 d, Z = 4, and ρ = 2.736 g/cm. It is shown that the crystal structure of the parent cubic Al(PO) modification can formally be considered an archetype for the formation of double isosymmetric tetraphosphates on its basis.
