Abstract

Invariance of stabilization diaquafluorosilicate by 18-crown-6 and synthesis of a complex pentafluorosilicate of hydroxonium with cis-syn-cis isomer dicyclohehane-18-crown-6 at interaction of crown-ethers with solutions of dioxide of silicon in fluorhydric acid reveal dominant influence of a spatial constitution of crown-ethers on an expedient of a complexing.
