摘要：
Preparation and properties of new alkali metal thionylimides MNSO (M = Na, Rb, Cs) and the known KNSO are reported. The characterization of the compounds was carried out by thermal analysis, IR-spectroscopy and X-ray powder diffraction. KNSO and RbNSO are isostructural (X-ray powder data): Pnma; KNSO: a = 766.81(2), b = 635.28(1), c = 704.22(2) pm; RbNSO: a = 800.21(1), b = 658.144(9), c = 731.39(1) pm. CsNSO (cubic; Pm $$($) over bar 3m; a = 464.78(3) pm) was described with a rotationally disordered [NSO](-)-anion. Force constants (GVFF-calculations) on the base of bond distances and bond angles of the anion were calculated.
