In the racemic title compound, C(34)H(22)Br(2)N(2)S·CDCl(3), pairs of diquinoline host mol-ecules form centrosymmetric brick-like dimers utilizing three different aryl edge-to-face inter-actions (EF(1-3)). The dimeric (EF)(6) (i.e. 2 × EF(1-3)) building blocks pack with the deuterochloro-form guest mol-ecules positioned near each of their corners. The Cl atoms of the latter are disordered over two sets of sites in a 0.53 (2):0.47 (2) ratio.
