Abstract
The crystal structure of the low-temperature form of (D5O2)[SbCl6] has been investigated using X-ray and neutron diffraction on powder samples and compared with the high-temperature phase. At 40 K in space group C2/c the lattice parameters are a = 11.938(1), b = 6.8968(4), c = 12.996(1) Å, β = 115.165(6)° in agreement with Z = 4. Although the phase transition corresponds to a 1st order process the similarity between high- and low-temperature form is remarkable.
