title: 7,7-Dichloro-1,6-dimethyl-2-oxa-5-thiabicyclo[4.1.0]heptane 5,5-dioxide and 6-chloro-2,3-dihydro-7-methyl-5-methylene-2H,3H,5H-1,4-dithiepine 1,1,4,4-tetraoxide.
abstract: The structures of a 2-oxa-5-thiabicyclo[4.1.0]heptane derivative, C(7)H(10)Cl(2)O(3)S, (I), and a 2H,3H,5H-1,4-dithiepine derivative, C(7)H(9)ClO(4)S(2), (II), are reported. The six-membered ring in (I) has an envelope conformation and the seven-membered ring in (II) adopts a chair conformation. There are no untoward intermolecular interactions in (I), but two Cl atoms make a short intermolecular contact across an inversion centre in (II), with a Cl.Cl distance of 3.2784 (9) A, some 0.22 A less than the sum of the van der Waals radii.
