Crystal structure of 6,6,12,12-tetrachlorotricyclo[8.2.0.04,7]dodecane-5,11-dione
The asymmetric unit of the title compound, C12H12Cl4O2, contains two crystallographically independent molecules with almost identical conformations (r.m.s. overlay fit for the non-hydrogen atoms = 0.059 Å). In each molecule, the central eight-membered ring has a distorted boat configuration, and two non-planar four-membered rings are fused on either side of the eight-membered ring. A weak C—H...O hydrogen bond links the two independent molecules. In the crystal, weak C—H...O hydrogen bonds link the molecules into a two-dimensional network parallel to (001).
