(4RS,1'RS)-METHYL 1-PHENYL-2-PIPERIDINO-ETHYL 6-DIMETHYL-4-(2-THIENYL)PYRIDINE-3,5-DICARBOXYLATE METHANOL SOLVATE, C27H32N2O4S.1.5.CH4O

The two independent molecules in the asymmetric unit have similar conf ormations. The 4-thienyl-1,4-dihydropyridine moieties adopt a flat boa t conformation commonly observed for 4-aryl-1,4-dihydropyridine deriva tives with the 4-thienyl group in a pseudo-axial orientation, The thie nyl and phenyl rings are perpendicular to each other, The six methanol molecules in the unit cell stabilize the crystal structure through in termolecular hydrogen bonds involving the N atoms of the dihydropyridi ne and the piperidine rings of both molecules.
