N2  - The crystal structure of the title compound, (c-C6H11)2P(S)C(S)SMe , has been determined and shows that the P(S)C(S)SC chromophore is situated on a crystallographic mirror plane with the cyclohexyl groups related to each other across this plane. Significant interatomic distances are: P=S 1.951(1), P-C 1.860(4), C=S 1.632(4) and C-S 1.700(4)&#506;. A resonance scheme involving the delocalization of &#960;-electrons over the CS2 moiety has been invoked to account for the observed C-S bond distances in the molecule. Crystals are orthorhombic, space group Pnma with unit cell parameters a 10.196(2), b 10.612(1) and c 15.370(3)&#506;, and Z 4. The structure was solved by direct methods and refined by a full-matrix least-squares procedure to final R 0.045, Rw 0.047 for 1191 reflections with I &#8805; 3.0&#963;(I).
