Abstract

Hexafluorosilicate (LH2)SiF6 and the cis-[SiF4(L)] chelate complex characterized by 19F NMR are products of reaction between hydrofluorosilicic acid and 1,10-phenanthroline (L). XRD findings show that the structure of (LH2)SiF6 is stabilized by NH···F hydrogen bonds (N···F 2.618(4), 2.676(4) Å) and CH···F contacts. The relative resistance of the cis-[SiF4(L)] complex to hydrolysis is associated with the chelate effect.
