N2 - The crystal structures of the cis- and trans-chlordanes and their photoisomers, C10H6Cl8, have been determined at 295(1) K by direct methods and refined by least squares. (1) cis-Chlordane: monoclinic P21/c, a l3·742(9), b 8·073(4), c 13·299(5) Å, β 93·81(4)°, Z 4. R 0·050 (1322 'observed' reflections). (2) trans-Chlordane: monoclinic, P21/a, a 15·762(5), b 7·694(2), c 12·526(4) Å, β 93·38(4)°, Z 4. R 0·052 (1678 'observed' reflections). (3) Photo-cis-chlordane: monoclinic, P21/n, a 12·403(3), b 13·830(4), c 8·310(2) Å, β 96·75(2)°, Z 4. R 0·056 (1501 'observed' reflections). (4) Photo-trans-chlordane: monoclinic, P21/c, a 16·521(5), b 6·699(2), c 14·431(6) Å, β 115·68(3)°, Z 4. R 0·047 (1302 'observed' reflections). An exceedingly long carbon-carbon bond (1.66(1) Å) is observed in (4).
