GeF4 analogues cis-[GeF4R2P(O)(CH2)nP(O)R2}] (R = Me or Ph, n = 1; R = Ph, n = 2) were similarly characterised and the structures of cis-[GeF4R2P(O)CH2P(O)R2}] (R = Me or Ph) determined. The reaction of R3AsO (R = Me or Ph) with SiF4 does not give simple adducts, but forms [R3AsOH]+ cations as fluorosilicate salts. SiF4 adducts of some ether ligands (including THF, 12-crown-4) were also characterised
