Key indicators: single-crystal X-ray study; T = 294 K; mean (C-C) = 0.005 Å; R factor = 0.046; wR factor = 0.132; data-to-parameter ratio = 13.5. The crystal structure of the title compound, C 8 HCl 4 NO 2 ÁC 3 H 7 NO, comprises tetrachloroisoindoline-1,3dione and N,N-dimethylformamide (DMF) solvent molecules, which are held together by N-HÁ Á ÁO, C-HÁ Á ÁO and C-HÁ Á ÁCl hydrogen bonds. The tetrachloroisoindoline-1,3-dione molecule is essentially planar. Related literature For the structure of
