“…1 that this condition is not fulfilled and that the conformation is of lower than C2v symmetry. The acsvalue (Jogun & Stezowski, 1979) obtained from the dihedral angles in Table 4, 3.3 °, is consistent with a structure that displays a good approximation to mirror symmetry.…”

The crystal structure of the title compound, C12H12CrO6S, Cr(CvH12OS)(CO) 5, has been determined at ca 120 K. The space group is P2~/c, Z = 4, with a = 13.154 (2), b = 6.4534 (6), c = 18.048 (2)/~, 13 = 101.43 (1) °. 9499 reflections (20mR x = 90 °, 2 = 0.71069 A) contributed to the refinement of 229 variables to give R = 0.049 and R w = 0.052. The complex displays approximate m molecular symmetry. The thietanone ligand, coordinated to the Cr through the S atom, Cr-S = 2.4241 (5)/k, displays similarities with the bonding geometry of cyclobutanone but the endocyclic bond angle about the carbonyl C atom is ca 10 ° larger and that about the S atom ca 11 ° smaller than their analogs in cyclobutanone.
