Abstract
A novel structure type has been established as a result of studying a non-merohedral microtwin of polyoxovanadate (K2ZnV5O14) by X-ray diffractometry (R = 0.0595). The new compound, synthesized under hydrothermal conditions in the ZnCl2–K2CO3–V2O5–H2O system, is characterized as follows: a = 8.066(5) A, b = 8.117(5) A, c = 9.236(5) A, β = 105.287(5)°, sp. P21/m, Z = 2, ρcalcd = 3.54 g/cm3. Edge-shared five-core “clusters” consisting of vanadium octahedra, between which ZnO4 tetrahedra (sharing vertices with octahedra) are located, form two-dimensional two-layer anion packets of the (ZnV5O14)2– composition, alternating along the c axis with layers of potassium atoms. Structural peculiarities determine the morphology and color of new-phase crystals.
