The 1,4-dihydro-pyridine ring adopts a flattened boat conformation. The benzene ring makes a dihedral angle of 33.36 (6) with the pyrazole ring. In the crystal, pairs of N - H?N hydrogen bonds link the molecules into inversion dimers. The dimers are stacked in column along the a axis through N - H?O and C - H?N hydrogen bonds. The crystal packing also features C - H?? inter-actions involving the pyrazole ring. Fun et al. 2012.Article
