Perhydrobenzimidazole-2-thione [PDF]
Acta Crystallographica Section E Structure Reports Online, 2009 The studied crystal of the title compound, C(7)H(12)N(2)S, is a racemic mixture of two isomers, viz. S,S and R,R. The two isomers share the same position on a mirror plane in the space group P2(1)/m; thus all atoms except one are disordered between two positions in a 1:1 ratio.
