1 Source of material

Nicotinaldehyde (1.07 g, 0.01 mol) was added to a stirred suspension of 4-chlorobenzohydrazide (1.71 g, 0.01 mol), in ethanol (10 mL), and the mixture was heated under reflux for 1 h. On cooling, the precipitated crude product was filtered, washed with ethanol, dried and recrystallised from ethanol to yield 2.44 g (94%) of the title compound as colourless plates. Melting point: 491–493 K (uncorrected). 1 H NMR (DMSO-d 6 , 500.13 MHz): d 11.02 (s, 1H, NH), 9.05 (CH=N), 8.99 (s, 1H, Pyridine–H), 8.48–8.62 (m, 2H, Pyridine–H), 7.96 (d, 2H, Ar–H, J = 7.2 Hz) and 7.45–7.59 (m, 2H, Ar–H & 1 Pyridine–H). 13 C NMR (DMSO-d 6 , 125.76 MHz): d 161.24 (C=O), 152.28, 149.20, 134.54, 129.80, 123.90 (Pyridine–C), 144.66 (CH=N), 138.0, 132.24, 130.08, 127.54 (Ar–C). Analysis (%) for C13H10ClN3O (259.69): C, 58.11 (Calc. 58.06); H, 4.14 (Calc. 4.18); N, 15.64 (Calc. 15.57).

2 Experimental details

The C-bound H atoms were geometrically placed (C–H = 0.95 Å) and refined as riding with U iso(H) = 1.2U eq(C). The N-bound H atoms were located in a difference map and refined freely. The crystal was refined as a two-component twin with the minor component = 0.2253(9).

3 Comment

Hydrazides and their N′-arylidene derivatives receive considerable interest for their remarkable biological activities [5, 6]. In addition, carbohydrazide-hydrazone derivatives are utilised as efficient intermediates for the synthesis of several biologically-active heterocyclic compounds [7, 8].

The synthesis and the crystal structure of a new N′-arylidene hydrazide derivative (I) are described herein along with an analysis of the molecular packing.

The molecular structures of the four independent molecules comprising the asymmetric-unit of (I) are shown in the upper four images of the figure (50% probability ellipsoids).

While to a first approximation, the molecules are similar to each other, having a strictly planar, central CN2O residue, are C-connected to a 4-chlorophenyl and to a 3-pyridyl residue via the imine bond, conformational differences are evident as shown in the overlay diagram (the color code for the O1- to O4-containing molecules is red, green, blue and pink, respectively; the images were overlaid so the 3-pyridyl rings are coincident). A small twist is noted about the C8–C9 bond as seen in the value of the N2–C8–C9–C10 torsion angle of 171.5(2)°, suggesting this part of the molecule is relatively planar; the comparable values for the O2- to O4-containing molecules are –171.1(2)°, 174.7(2)° and –176.9(2)°, respectively. A greater twist is seen about the C4–C7 bond, i.e. C5–C4–C7–O1 = 163.5(2)°; the values for the O2- to O4-containing molecules are −170.8(3)°, −159.0(2)° and 174.0(3)°, respectively. These differences manifest in a range of dihedral angles between the terminal rings, i.e. 25.04(11)°, 11.79(12)°, 32.82(12)° and 15.16(12)°, respectively. While the differences in conformation confirm the choice of crystal symmetry, these are unlikely to have any chemical significance.

There are three closely related 3-pyridyl derivatives in the literature, which differ only in the nature of the substitution at the 4-position of the phenyl ring, i.e. with H [9], NMe2 [10] and NO2 [11] cf. Cl in (I). For comparison with (I), the values of the dihedral angles between the terminal rings are 47.79(14)°, 5.19(8)° and 28.29(4)°, respectively, highlighting the variability of conformations in this class of compound, at least in the solid-state. The occurrence of a Z' > 1 is not unusual in this class of compounds [12].

A supramolecular chain featuring amide-N–H⋯N(pyridyl) hydrogen bonds is prominent in the molecular packing, as illustrated in the lower view of the figure. The chains involve all four independent molecules [a representative interaction is H1n⋯N12 i [N1–H1n⋯N12 i : H1n⋯N12 i  = 2.16(3) Å, N1⋯N12 i  = 3.035(3) Å with angle at H1n = 167(3)° for symmetry operation (i): x, 3/2 − y, 1/2 + z].

Molecules assemble into supramolecular layers in the ac-plane. Prominent interactions between the twisted chains along the a-axis include pyridyl-C–H⋯O(carbonyl) [C12–H12⋯O2 ii : H12⋯O2 ii  = 2.47 Å, C12⋯O2 ii  = 3.176(3) Å with angle at H12 = 131° for (ii): 1 + x, 3/2 − y, −1/2 + z] and pyridyl-C–H⋯N(imine) [C49–H49⋯N11 i : H49⋯N11 i = 2.51 Å, C49⋯N11 i  = 3.415(3) Å with angle at H49 = 158°] interactions. The 4-chlorophenyl rings project alternatively to either side of the layer and these inter-digitate with adjacent layers along the b-axis with close phenyl-C–Cl⋯π(phenyl, pyridyl) contacts [closest contact: C1–Cl1⋯Cg(N9-pyridyl) iii : Cl1⋯Cg(N9-pyridyl) iii  = 3.4860(12) Å with angle at Cl1 = 170.47(9)° for (iii): 1 − x, 1/2 + y, 1/2 − z].
