C~H IzN208, M,. = 220.3, orthorhombic, P2~2121, a = 8.063 (3), b = 12.461(4), c = 21.805 (5) A,Z = 8 (two molecules in the asymmetric unit). Final R = 0.040 for 1496 intensities. Both molecules in the asymmetric unit possess short intramolecular C=O.-.S-C close contacts of 2.679 (5) and 2.655 (5) A with C-S... O angles of 164.1 (4) and 164.9(4) ° , respectively, suggesting a single-bond/no-bond resonance. These close contacts and their environments are discussed in a comparison with structures which exhibit C=O...S-X (X = S, O, N and C) distances in the range 2.0-3.0 A.
