The λ 6 Si-silicate [Cs(18-crown-6)] 2 [Si(OSO 2 CH 3 ) 6 ] ( 1 ) was synthesized by treatment of Si 2 Cl 6 with Cs[OSO 2 CH 3 ] in the presence of 18-crown-6. Compound 1 is the first example of a λ 6 Si-silicate with a methanesulfonate ligand. It was characterized by NMR spectroscopy and by single-crystal X-ray diffraction. The solid-state structure of 1 consists of discrete [Si(OSO 2 CH 3 ) 6 ] 2– anions and two [Cs(18-crown-6)] + cations (triclinic space group, P1¯$P\overline{1}$, Z = 1).
