A second monoclinic polymorph of 2-(3,5-dimethyl-1H-pyrazol-1-yl)-2-hydroxyimino-N'-[1-(pyridin-2-yl)ethylidene]acetohydrazide
[Introduction] The title compound, C 14 H 16 N 6 O 2 , is a second monoclinic polymorph of 2-[1-(3,5-dimethyl)pyrazolyl]-2-hydroxyimino- N 0 -[1-(2-pyridyl)ethylidene] acetohydrazide, with two crystal- lographically 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. E 68 , 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 N hydrogen bonds into zigzag chains extending along the b axis. peerReviewed
