Abstract
We report on the pulsed neutron powder diffraction study of the high and low temperature phases of [Pt(en)2][Pt(en)2Cl2](CIO4)4 (where en=ethylenediamine), referred to as PtCI, that undergoes a structural phase transition at 19.8°C. It is shown that the high and low temperature phases are orthorhombic and monoclinic, respectively. The transition is associated with a very large shear (3.9°) and the translational group of the low temperature phase is not a subgroup of the high temperature phase translational group this supports the first order character proposed earlier.
