摘要：

The crystal structures of CClF2COOH (monoclinic, space group P2(1)/c, Z = 4 molecules per unit cell; lattice parameters = 8.242, b = 5.658, c = 9.435 Angstrom and beta = 102.58 degrees) and CCl2FCOOH (orthorhombic, Pbcn, Z = 16; a = 16.158, b = 5.976 and c = 20.93 Angstrom) have been determined at -150 degrees C. The molecules form hydrogen-bonded cyclic dimers in CC1F,COOH (just as in solid CF3COOH and CCl3COOH), but strongly folded chains of a new type in CCl2FCOOH.
