(Received 2 April 2013; accepted 8 April 2013; online 20 April 2013)

The title compound, C14H16N6O2, is a second monoclinic polymorph of 2-[1-(3,5-dimeth­yl)pyrazol­yl]-2-hy­droxy­imino-N′-[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[Plutenko, M. O., Lampeka, R. D., Haukka, M. & Nordlander, E. (2012). Acta Cryst. E68, o3381.]). 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⋯N hydrogen bonds into zigzag chains extending along the b axis.

Comment top

Oximes are one of the most efficient bridging ligands class. Polydentate ligands containing both oxime and other donor functions are of special interest due to their potential for the bridging coordination modes and mediation of strong magnetic superexchange between metal ions (Penkova et al., 2009; Kanderal et al., 2005; Moroz et al., 2010). Oxime ligands having the pyridyl groups in the molecule have been used in the preparation of complexes with a variety of transition metals, binding to metals in different modes most commonly as chelates or serving as bridge to metals, and the resulting species have been employed in molecular magnetism and supramolecular chemistry (Moroz et al., 2010, 2012). Herein we report a second polymorph of 2-[1-(3,5-dimethyl)pyrazolyl]-2-hydroxyimino-N'-[1-(2-pyridyl)ethylidene] acetohydrazide (II) (Fig. 1). In comparison, the first polymorph I described previously (Plutenko et al., 2012), crystallized in monoclinic space group Cc, Z = 4, while the title compound II crystallized in space group P21/n with Z = 8 (Fig. 1).

Bond lengths N-N', N-C and C-O of the amide group are 1.3693 (10), 1.3589 (11) and 1.2162 (11) respectively for molecule A and 1.3705 (11), 1.3603 (11) and 1.2156 (11) respectively for molecule B. Such bond lengths are typical for the protonated amide groups (Kanderal et al., 2005). The oxime group is situated in anti- position to the amide group which was shown earlier in the structures of the amide derivatives of 2-hydroxyiminopropanoic acid (Onindo et al., 1995; Sliva et al., 1997; Fritsky et al., 2006). The NC(=NOH)C(O)NH fragment deviates from planarity because of a twist between the oxime and the amide groups about the C(8)-C9 and C(22)-C(23) bonds; the O(1)-C(8)-C(9)-N(3) and O(22)-C(23)-C(9)-N(8) torsion angles are -175.953 (2)° and 164.073 (2)°. The bond lengths N-O and C-N of the oxime group are 1.3615 (9) and 1.2836 (11) Å respectively for A and 1.3645 (10) and 1.2819 (11) Å respectively for B. The bond lengths and angles within the oxime groups are normal and comparable to those in the related structures (Świątek-Kozłowska et al., 2000; Mokhir et al., 2002; Fritsky et al., 1998). The C=N and N—O bond lengths in the oxime moiety of the molecule clearly indicates that the oxime group exists in the nitroso rather than in the isonitroso form (Duda et al., 1997; Kanderal et al., 2005; Fritsky et al., 2004).

The C-C, C-N and N-N' (1,331 (0) – 1,409 (0) Å) bond lengths in the pyrazole ring exhibit normal values (Penkova et al., 2010). The angles C-C'-C'', C-N-C', N-C-C' and N-N'-C are near 108°. The pyrazole ring deviates from the plane formed by other atoms of ligand molecule. The N(4)-C(9)-N(5)-N(6) and torsion angles are -103.589 (2) and 105.359 (2)° respectively. The C-N and C-C bond lengths in the pyridine rings are normal for 2-substituted pyridine derivatives (Fritsky et al., 2000; Krämer et al., 2000; Strotmeyer et al., 2003).

In the crystal packing both molecules A and B are each connected by N-H···N hydrogen bonds, where the oxime nitrogen acts as donor and the pyrazole nitrogen atom acts as acceptor (Table 1). Thus, zig-zag supramolecular chains along b-axis are formed.

Experimental top

The present compound was synthesized according to Plutenko et al. (2012):

Synthesis of ethyl 2-[1-(3,5-dimethyl)pyrazolyl]-2-hydroxyiminoacetate: A mixture of ethyl 2-chloro-2-hydroxyiminoacetate synthesized according to Kozikowski et al. (1983) (0.906g, 6 mmol) and 3,5-dimethylpyrazol (1.152g, 12 mmol) in 10 ml of chloroform was left for evaporation in the air overnight. The resulting precipitate was crystallized from water. Yield: 1.12g (88 %).

Synthesis of 2-[1-(3,5-dimethyl)pyrazolyl]-2-hydroxyiminoacetohydrazide: A solution of hydrazine hydrate (0.57 ml, 60%, 10.6 mmol) in water was added to a solution of ethyl 2-[1-(3,5-dimethyl)pyrazolyl]-2-hydroxyiminoacetate (1.12g, 5.3 mmol) in methanol (30 ml). The resulting mixture was heating under reflux for 1.5 hours. After that solvent was evaporated and product was crystallized from methanol. Yield 0.5g (48 %).

Synthesis of 2-[1-(3,5-dimethyl)pyrazolyl]-2-hydroxyimino-N'-[1-(2-pyridyl)ethylidene]acetohydrazide: A solution of 2-[1-(3,5-dimethyl)pyrazolyl]-2-hydroxyiminoacetohydrazide (0.5g, 2.54 mmol) in methanol (30 ml) was treated with 2-acetylpyridine (0.307g, 2.54 mmol) and the mixture was heated under reflux for 3 hours. After that the solvent was evaporated in vacuum and the product was crystallized from methanol. Yield 0.65g (85 %).

Refinement top

OH, NH and CH3 hydrogen atoms were located from difference Fourier maps, other hydrogen atoms were positioned geometrically and all but H(N) and H(O) were refined at idealized positions riding on the parent atoms, with C—H = 0.95–0.98 Å, and Uiso = 1.2–1.5 Ueq(parent atom). H(N) and H(O) atoms were refined freely with Uiso(H) = 1.2Ueq(N) or 1.5Ueq(O). All CH3 hydrogen atoms were allowed to rotate but not to tip. The highest peak is located 0.74 Å from atom C9 and the deepest hole is located 1.03 Å from atom N4.

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2sigma(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
