Single-crystal X-ray and neutron powder diffraction investigation of the phase transition in tetrachlorobenzene

Autor: William I. F. David, Richard M. Ibberson, Kenneth Shankland, Derek A. Tocher, Sarah A. Barnett, Charlotte K. Broder

The polymorphic phase transition of 1,2,4,5-tetrachlorobenzene (TCB) has been investigated using neutron powder diffraction and single-crystal X-ray diffraction. The diffraction experiments show a reversible phase change that occurs as a function of
