Abstract top

The asymmetric unit of the title compound, C22H23N5O2, contains two independent molecules with similar conformations; the terminal pyridine rings are oriented at dihedral angles of 23.99 (8) and 18.07 (8)° with respect to the central benzene ring in one molecule and 28.99 (8) and 23.22 (8)° in the other. In the crystal, N-H...O and weak C-H...O hydrogen bonds link the molecules into a three-dimensional supramolecular structure. Weak intermolecular C-H...[pi] interactions are also observed in the crystal.

Comment top

Bis(2-pyridinecarboxamide) derivatives comprise a large group of organic compounds that are ideal for the mono- or dinuclear chelation of metal ions (Cornman et al., 1999; Song et al., 2010; Singh et al., 2008). In order to explore coordination chemistry of bis(pyridinecarboxamide) ligands, we have synthesized the title compound (I) and report here its crystal structure.

The asymmetric unit of the title compound (I), C22H23N5O2, contains two independent molecules with the similar structure, two terminal pyridine rings are oriented with respect to the central benzene ring at 23.99 (8) and 18.07 (8)° in one molecule and at 28.99 (8) and 23.22 (8)° in the other (Fig. 1). Every independent molecule contains two symmetrical N-ethyl(pyridine-2-carboxiamide) moieties linked by a phenylamino bridge. It is noteworthy that the CO bonds are oriented trans to the pyridine nitrogen atom, which are in accord with those reported for previous structures (Munro et al., 2010; Yan et al., 2012). In the crystal, intermolecular N–H···O (Fig. 2) and weak C—H···O hydrogen bonds (Fig. 3) link the molecules into the three-dimensional supramolecular structure. The crystal packing exhibits also weak intermolecular C–H···π interaction, proved by short distance C30–H30B···Cg5 [3.6584 (18) Å] and C8–H8A···Cg6 [3.6468 (18) Å], where Cg5 and Cg6 are the centroids of the C9–benzene and C31–benzene rings, respectively [symmetry code: (iv) x+1/2, –y+1/2, z+1/2; (v) x–1/2, –y+1/2, z–1/2] (Table 1).

Experimental top

N-(3-Dimethylaminopropyl)-N-ethylcarbodiimide hydrochloride (EDCI, 375 mg, 1.95 mmol) and hydroxybenzotriazole (HOBt, 440 mg, 3.26 mmol) were added to a solution of picolinic acid (200 mg, 1.62 mmol) in dry DMF (10 ml) at room temperature. After the mixture was stirred for 30 min, N1-(2-aminoethyl)-N1-phenylethane-1,2-diamine (133 mg, 0.74 mmol) was added (Lee et al., 2006). The reaction mixture was stirred overnight under N2 atmosphere. H2O (30 ml) was added to quench the reaction, and the mixture was extracted with ethyl acetate (3×20 ml). The combined organic phase was washed with brine, dried over Na2SO4, filtrated and concentrated in vacuum. The residue was purified by column chromatography (PE:EA = 2:1~1:2) to give compound (I) (264 mg, yield: 91.8%) as a white solid. Colorless single crystals suitable for X-ray structural analysis were obtained by slow evaporation of a mixture solution of dichloromethane and methanol at room temperature. 1H NMR (400 MHz, CDCl3): 3.48~3.61 (m, 8H), 6.62 (t, J = 8.0 Hz, 1H), 6.85 (d, J = 7.2 Hz, 2H), 7.15 (t, J = 8.0 Hz, 2H), 7.28~7.32 (m, 2H), 7.73 (t, J = 8.0 Hz, 2H), 8.09 (d, J = 7.2 Hz, 2H), 8.30~8.40 (m, 4H).

Refinement top

H-atoms were placed in calculated positions (C–H 0.93–0.97 Å, N–H 0.86 Å), and were included in the refinement in the riding model, with Uiso(H) = 1.2Ueq(C,N).

Special details top

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