A family of alkali metal tin(II) fluorides, ASnF{sub 3} (A=Na{sup +}, K{sup +}, Rb{sup +}, or Cs{sup +}), has been synthesized through a low temperature solvothermal technique. A fluorine free solvent, methanol, was used in the synthesis. NaSnF{sub 3}, KSnF{sub 3}, and RbSnF{sub 3} have been reported previously; however for RbSnF{sub 3} the reported space group is incorrect. CsSnF{sub 3} is a new alkali tin(II) fluoride, and exhibits a ‘zero-dimensional’ crystal structure with isolated SnF{sub 3}{sup −} anions separated by Cs{sup +} cations. In addition to the synthesis, infrared, UV–vis, thermogravimetric and differential thermal analysis measurements were performed. - Graphical abstract: Ball-and-stick diagrams of CsSnF{sub 3}. Display Omitted - Highlights: • A family of ASnF{sub 3} (A=Na{sup +}, K{sup +}, Rb{sup +} or Cs{sup +}) has been synthesized solvothermally at low temperatures. • Fluorine-free solvent, methanol, was used instead of conventional fluorinating agents. • RbSnF{sub 3} described in the correct space group exhibits infinite chains of corner-sharing SnF{sub 4} polyhedra. • New CsSnF{sub 3} exhibits a ‘zero-dimensional’ crystal structure consisting of isolated SnF{sub 3}{sup −} anionic polyhedra.
