The title compound, C(13)H(12)N(4)O, crystallizes with two independent mol-ecules in the asymmetric unit. The compound crystallizes as the ZE isomer, where Z and E refer to the configuration around the C=N and N-C bonds, respectively, with an N-H⋯N(py) (py is pyridine) intra-molecular hydrogen bond. The dihedral angles between the least-squares planes through the semicarbazone group and the pyridyl ring are 22.70 (9) and 27.26 (9)° for the two mol-ecules. There are intermolecular N-H⋯O hydrogen bonds. |
