Abstract

The crystal structure of a new tubular silicate of potassium, sodium, and manganese, K(K0.72Na0.28)Mn[Si4O10], prepared in the form of single crystals by the hydrothermal method in the MnCl2–NaNO3–SiO2–K2CO3–H2O system, has been studied by X-ray diffraction using synchrotron radiation at low temperatures (λ = 0.64066 Å, T = 100 K, R = 0.0248): a = 7.0182(4) Å, b = 8.1642(7) Å, c = 9.9670(11) Å, α = 104.816(8)°, β = 101.099(8)°, γ = 113.558(8)°, sp. gr.
