The dihydropyridine ring adopts an E 4 conformation. In the crystal, classical O-H?N, O-H?O and N-H?O hydrogen bonds, as well as C-H?O and C-H?S contacts, connect the molecules into a three-dimensional network.data-to-parameter ratio = 16.9disorder in main residuemean ?(C-C) = 0.002 ÅR factor = 0.040single-crystal X-ray studyT = 200 KwR factor = 0.111
