title: 3-Methyl 5-isopropyl 2-methoxyiminomethyl-6-methyl-4-(3-nitrophenyl)-1,4-dihydropyridine-3,5-dicarboxylate.
abstract: The crystal structure of the title compound, C(20)H(23)N(3)O(7), consists of relatively isolated molecules. The substituted 1,4-dihydropyridine ring adopts a flattened boat conformation. Both ester groups, at positions 3 and 5, have cis,cis geometry. The phenyl ring is nearly planar and is approximately perpendicular to the 1,4-dihydropyridine ring (dihedral angle 87.70 degrees ).
