Abstract
2,3,5,6-Tetrakis(trifluoromethyl)terephthaloyl difluoride, C12F14O2, c rystallizes in space group Fddd, which requires the molecule to have 2 22 symmetry. This is achieved by disordering the F, O and C atoms of t he acyl halide group. The bulky CF3 groups cause a slight distortion f rom planarity of the six-membered ring and they are forced out of copl anarity with the ring. The plane of the -(C=O)-F group is rotated 62 d egrees from the plane of the phenyl ring.
