3-Oxo-5-(piperidin-1-yl)-2,3-dihydro-1H-pyrazole-4-carbonitrile. | LitMetric

In the title compound, C(9)H(12)N(4)O, the piperidine ring adopts a chair conformation and makes a dihedral angle of 42.49 (11)° with the approximately planar pyrazole moiety [maximum deviation = 0.038 (2) Å]. In the crystal, N-H⋯O and N-H⋯N hydrogen bonds and a weak C-H⋯O inter-action link the mol-ecules into sheets lying parallel to (110).
