2-[4-(2-{5-tert-Butyl-2-chloro-3-[2-(3-pentyl-1,3-benzothia­zol-2-yl­idene)ethyl­idene]cyclo­hex-1-en­yl}ethen­yl)-3-cyano-5,5-dimethyl­furan-2-yl­idene]malono­nitrile

In the title mol-ecule, C36H39ClN4OS, the non-aromatic part of the cyclo-hex-1-enyl ring and the attached tert-butyl group are disordered over two conformations with occupancy ratios of 0.52 (3):0.48 (3) and 0.53 (3):0.47 (3), respectively. The polyene chain single- and double-bond dimensions contrast with a closely related compound [Bouit et al. (2007 ▶). Chem. Mater.19, 5325-5335] with an approximate 19° twist between donor and acceptor ends of the mol-ecule, related to the additional intra-molecular C-H⋯S inter-action. In the title compound, the mol-ecules pack into dimeric units about centres of symmetry utilizing weak C-H⋯N(cyano) and C-H⋯O attractive inter-actions, building both chain and ring motifs about the centres [R2(2)(8) and R2(2)(9)]. Adjacent dimeric sets then form a herringbone configuration.
