The title compound S,S?bis(8-quinolyl)-1,8-dithiaoctane crystallizes in the monoclinic system, space group P21/n with a = 7.537(1), b = 20.434(3), c = 13.857(2) , = 97.102(3)? V = 2117.8(5) 3, Dc = 1.269 g/cm3, Z = 4, C24H24N2S2, Mr = 404.57, (MoK? = 0.263 mm-1 and F(000) = 856, and its structure was refined to R = 0.0417 and wR = 0.1077 for 2814 observed reflections (I > 2(I)). The compound crystallizes in conformations A and B with equal occupation ratio. A acts as both a donor and acceptor in the CH… interactions, but B only acts as a donor. Edge-to-face CH…?interactions between AA along the a axis and BABA along the c axis result in an infinite layered-structure in the ac plane. The title compound S, S?
