Abstract

The phase transition in (CD₃ND₃)₂ [SnCI₆], for which the fluctuation of the order parameter is exceptionally strong among molecular systems, was studied by high-resolution neutron diffraction. The transition was accompanied by contraction of the a and expansion of the c axes as T_c = 154 K was traversed from above. The square root of the c expansion was proportional to the occupancy of one of the deuterium sites which is the order parameter of the transition. The mechanism of this coupling is discussed.
