Benzyl 2-(4-bromo­anilino)-4,4-dimethyl-6-oxo­cyclo­hex-1-enecarbodithio­ate: second triclinic polymorph

The title structure, C(22)H(22)BrNOS(2), is a triclinic modification. Whereas the other reported modification crystallizes with just one mol­ecule in the asymmetric unit, the present modification has Z′ = 2. The six-membered cyclo­hexene ring adopts an envelope conformation, with the C atom bearing the two methyl groups representing the flap. This atom deviates by 0.674 (4) Å from the plane passing through the other five atoms of the ring (r.m.s. deviation = 0.027 Å). For the second independent mol­ecule, the deviation is 0.669 (3) Å and the r.m.s. deviation is 0.010 Å. The mol­ecular conformation of both mol­ecules is stabilized by intra­molecular N—H⋯S hydrogen bonds.
