title: N,N-Diethyl-2,6,6-trimethyl-4-(3-nitrophenyl)-5-oxo-1,4,5,6,7,8-hexahydroquinoline-3-carboxamide.
abstract: The title compound, C(23)H(29)N(3)O(4), has potential calcium modulatory properties. The conformation of the 1,4-dihydropyridine ring is unusual in that it is planar, instead of the usual shallow boat. The 3-nitrophenyl substituent is in the synperiplanar orientation with respect to the dihydropyridine ring plane. The oxocyclohexene ring has a distorted envelope conformation, with the out-of-plane atom being disordered on opposite sides of the ring plane. The molecules are linked into chains by intermolecular hydrogen bonds.
