1,4-Dichloro-2,3-bis-(chloro-meth-yl)butane.

The title compound, C6H10Cl4, adopts a geometric arrangement with two C-Cl bonds anti-periplanar to C-H bonds and the other two anti-periplanar to C-C bonds. While minimising steric replusion, this arrangement still gives rise to some intramolecular C-H⋯Cl contacts. In the crystal, mol-ecules are connected into a three-dimensional architecture via further C-H⋯Cl contacts.
