Octahedral Structure

Silicon tetrafluoride and hydrazine react in a vacuum to produce a white, non-volatile, solid, 1:2 complex, SiF4.2N2H4. This compound sublimes with decomposition above 200° and is insoluble in common organic solvents. It reacts with (a) 55% hydrofluoric acid, (b) anhydrous hydrogen chloride, (c) ethylenediamine, (d) ammonia, and (e) boron trifluoride, producing: (a) (N2H5+)2SiF62−, (b) N2H5+Cl−, (c) SiF4.NH2(CH2)2NH2, (d) SiF4.2NH3, and (e) BF3.N2H4. A comparison of the infrared spectra of SiF4.2NH3, SiF4.2N2H4, and SiF4.NH2(CH2)2NH2 suggests that all three complexes have cis octahedral structure.
