The title compound, C29H35N3, is the product of the condensation reaction between 2,6-diacetyl­pyridine and 2,6-diethyl­aniline. In the mol­ecule, the pyridyl ring is coplanar with the imino functional groups [torsion angles in the range 177.1 (2)–179.9 (2)°. The two 2,6-diethyl-substituted benzene rings are approximately perpendicular to the ethyl­idenepyridine central core, the dihedral angles being 88.7 (1) and 88.4 (1)°, respectively.

Comment top

Luminescent coordination compounds based on pyridine-type ligands have attracted intensive attention due to their potential application in areas of sensor technologies and electro-luminescent devices (Tang & VanSlyke, 1987; Wang, 2001). In order to explore potential luminescent complexes of this type, we prepared a series of bis(iminoalkyl)pyridine ligands by the condensation of 2,6-diacetylpyridine with the corresponding aniline in methanol (Fan et al., 2004). We report here the crystal structure of one of them, (I).

The molecular structure of (I) is shown in Fig. 1 and selected bond distances are given in Table 1. The pyridyl ring is coplanar with the two imino functional groups. The two imino CN bonds have typical double-bond characteristics, with bond lengths of 1.272 (3) and 1.275 (2) Å, which are similar to that in BIP1, 1.266 (4) (Mentes et al., 2001) and in 2,6-bis[1-(2,6-dimethylphenylimino)ethyl]pyridine, 1.265 (2) and 1.271 (2) Å (Huang et al., 2006). Compound (I) possesses a structure which approximates Cs symmetry about a plane bisecting the central pyridyl ring. The two 2,6-diethyl-substituted phenyl rings are approximately perpendicular to the ethylidenepyridine ring, with the dihedral angles being 88.7° and 88.4°.

Experimental top

The title compound was synthesized according to the literature method of Fan et al. (2004). To a solution of 2,6-diethylpyridine (1.5 g, 9.2 mmol) in absolute methanol (40 ml) was added 2,6-diethylaniline (4.6 ml, 27.7 mmol). After the addition of several drops of formic acid, the reaction mixture was refluxed for 24 h and then allowed to cool down to room temperature. The crude product precipitated as a yellow powder. Pure (I) was obtained as yellow block crystals in 84% yield (3.3 g) upon recrystallization from methanol, giving single crystals suitable for X-ray diffraction.

Refinement top

The C-bound H atoms were positioned geometrically with C—H = 0.93–0.97 Å, and allowed to ride on their parent atoms with Uiso(H) = 1.5Ueq(carrier C) for methyl groups and Uiso(H) = 1.2Ueq(carrier C) otherwise.
