摘要:

The setting in of orientational order in 1,2,3-trichloro-4,5,6-trimethyl benzene at low temperature has been studied by single crystal X-ray diffraction. At 173 K, the supercell is pseudo-monoclinic with two independent molecules in the asymmetric unit. A group refinement has been made. The superstructure is an antiferroelectric arrangement with two kinds of domains.
