Deskripsi
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.
