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.
