Вперше синтезовано новий подвiйний фосфат NaMn6P7O24 та проведено повний рентгеноструктурний аналiз його монокристалiв. Дослiджено деякi фiзико-хiмiчнi властивостi отриманої сполуки.
The RSA of obtained phosphate NaMn6P7O24 is realized. The crystals are monoclinic (P21/m). The parameters of a cell are: a = 0.53584 nm, b = 2.6697 nm, c = 0.65759 nm, β = 107.226º; Z = 2, ρdet = 3.584 g/cm³. The base of the structure is a frame which consists of octahedra MnO6 (connected via common edges), discrete anion groups [P3O10] (which are situated in the plane of symmetry), and anions P2O7.
