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 mol­ecule, C₃₆H₃₉ClN₄OS, the non-aromatic part of the cyclo­hex-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 mol­ecule, related to the additional intra­molecular C—H...S inter­action. In the title compound, the mol­ecules pack into dimeric units about centres of symmetry utilizing weak C—H...N(cyano) and C—H...O attractive inter­actions, building both chain and ring motifs about the centres [R₂²(8) and R₂²(9)]. Adjacent dimeric sets then form a herringbone configuration.
