Ethyl 2-[2-(2,4-diphenyl-3-aza­bicyclo­[3.3.1]nonan-9-yl­idene)hydrazin-1-yl]-4-methyl-1,3-thia­zole-5-carboxyl­ate di­methyl­formamide monosolvate

Abstract: In the title mol­ecule, C27H30N4O2S·C3H7NO, the fused piperidine and cyclo­hexane rings adopt a twin chair conformation and the phenyl groups occupy equatorial sites. The phenyl rings make a dihedral angle of 40.74 (2)°. In the crystal, the di­methyl­formamide solvent mol­ecule is connected to the main mol­ecule by an N-H...O hydrogen bond. An additional N-H...O hydrogen bond connects mol­ecules into chains along [100]. Pairs of weak C-H...O hydrogen bonds connect inversion-related chains. The ethyl group was refined as disordered over two sets of sites with an occupancy ratio of 0.660 (17):0.340 (17).
