摘要：
The title compound, C14H16N6O2, is a second monoclinic polymorph of 2-[1-(3,5-dimethyl)pyrazolyl]-2-hydroxyiminoN'-[1-( 2-pyridyl) ethylidene] acetohydrazide, with two crystallographically independent molecules per asymmetric unit. The non-planar molecules are chemically equal having similar geometric parameters. The previously reported polymorph [Plutenko et al. ( 2012). Acta Cryst. E68, o3281] was described in space group Cc ( Z = 4). The oxime group and the O atom of the amide group are anti with respect to the C-C bond. In the crystal, molecules are connected by N-H center dot center dot center dot N hydrogen bonds into zigzag chains extending along the b axis.
