Anhydrous fluorosulfates of sodium(I) and thallium(I) have been structurally characterized for the first time; structure of a novel polymorphic form of rubidium(I) fluorosulfate is also reported. NaSO3F is hexagonal (P63/mmc, a = b = 5.4812(2) Å, c = 6.5172(3) Å, Z = 2), while RbSO3F and TlSO3F are orthorhombic an both adopt the Pnma space group, but despite similar ionic radii of metal cations they are not isostructural with each other (Rb: a = 8.7812(7) Å, b = 6.0318(6) Å, c = 7.5108(6) Å, Z = 4; Tl: a = 5.2205(3) Å, b = 5.5141(2) Å, c = 13.4378(7) Å, Z = 4). The three fluorosulfates studied here complete the list of fluorosulfates of monovalent metals, for which the crystal structures have been determined.
