- Abstract
- A single-crystal X-ray diffraction study of novel natrural uranyl-vanadate phase, discovered in the rocks of the Hatrurim formation and close in composition to the mineral strelkinite, has been carried out. The studied crystal is orthorhombic, space group Pccn, a = 13.355(3), b = 8.2368(7), c = 10.6180(11) Å, V = 1168.0(3) Å3, Z = 4, R1 = 0.179, CSD2409185. The crystall chemical formula obtained in a course of the X-ray diffraction experiment is (Na1.12K0.88)(UO2)2(V2O8), which is in a good agreement with that calculated from the chemical analysis data (Na1.16K0.78) Σ1.94(U1.005O2)2(V2O8). Despite the high convergence parameters, the structural model can be considered as quite reliable, especially in the part of the uranyl-vanadate layers of the carnotite type. Strong diffuse scattering does not allow more precise refinement of the partially disordered sites of the interlayer cations. The mutual arrangement of the vanadate pyramids dimers in neighbor layers is unique in comparison with the crystal structures of other carnotite group minerals and related synthetic phases. It can be assumed that the studied phase is potentially a new mineral species - a dehydrated analogue of strelkinite - which cannot be approved yet due to the lack of sufficient material. Then, by analogy with tyuyamunite-metatyuyamunite pair, it can be called "metastrelkinite".
