Abstract
The title compound, C6Cl10, cystallizes in a nearly C2-symmetrical gauche conformation. Both trichlorovinyl groups are nearly planar [Cl—C—C—Cl torsion angles = −178.47 (12) and −179.93 (11)°] and the lengths of their C—Cl bonds increase from the terminal trans and cis C—Cl bonds to the internal bonds. The Cl—C—Cl bond angles of the terminal dichloromethylene units are compressed to 111.75 (11) and 111.40 (11)°.

The title compound, C6Cl10, cystallizes in a nearly C2symmetrical gauche conformation. Both trichlorovinyl groups are nearly planar [Cl—C—C—Cl torsion angles = À178.47 (12) and À179.93 (11)] and the lengths of their C—Cl bonds increase from the terminal trans and cis C—Cl bonds to the internal bonds
