inorganic compounds
The crystal structure of [Co(NO2)(NH3)5](SiF6) has been determined at 293 and 150K. The complex cations in the structure are linked by N—HF
hydrogen bonds to the (SiF6)2− anions and by N—HO hydrogen bonds
to other cations. The role of these hydrogen bonds and of the repulsive
OF interactions in the anisotropy of the structural distortion on cooling
is discussed.
