title: Dimethyl 1-(2-cyano-benz-yl)-1H-pyrazole-3,5-dicarboxyl-ate.
abstract: In the mol-ecule of the title compound, C(15)H(13)N(3)O(4), the dihedral angle between the pyrazole and benzene rings is 79.89 (6)°. An intra-molecular C-H⋯O hydrogen bond is present. The crystal structure is stabilized by π-π stacking inter-actions between centrosymmetrically related pyrazole rings with a centroid-centroid distance of 3.500 (3) Å.
