Article abstract of DOI:10.1080/15421400701693534

The title compound, C15H16N2O3, was synthesized, characterized spectroscopically, and finally confirmed by X-ray diffraction studies. The compound crystallizes in the monoclinic space group P21/n with cell parameters a=10.314(9) , b=17.976(15) , c=12.762(11), =113.331(3), Z=4, and V=2173(3) 3. The dihydropyridine ring in the structure is in a flattened-boat conformation. The 2-nitrophenyl ring is orthogonal to the 1,4-dihydropyridine ring. The structure exhibits an intermolecular hydrogen bond of the type C-HO.
