(Received 11 December 2013; accepted 13 December 2013; online 18 December 2013)

In the title mol­ecule, C27H31N3, the imine C=N groups are orientated anti to the pyridine N atom, with N—C—C—N torsion angles of −164.91 (11) and −170.53 (10)°. In the crystal, mol­ecules are connected by weak C—H⋯N and C—H⋯π inter­actions parallel to the b axis.

Comment top

Ligands based on tridentate di­imino pyridines, containing bulky aryl substituents, find widespread application in organometallic chemistry and catalysis (Britovsek et al., 1999; Dias et al., 2001; Liu et al., 2009; Wieder et al., 2011; Darmon et al., 2012). As part of our work using these ligands, we have determined the structure of the title compound (I).

Compound (I) adopts a conformation with the donor imine and pyridine groups orientated in opposing directions, with N—C—C—N dihedral angles of -164.91 (11)° and -170.53 (10)° (Fig. 1). This conformation contrasts with that observed on coordination of (I) to transitions metals (Britovsek et al., 1999; Wieder et al., 2011).

In the crystal the molecules are connected by weak C—H···N and C—H···π inter­actions, Table 1, parallel to the b axis (Fig. 2).

Experimental top

Synthesis and crystallization top

The title compound (I) was prepared as previously described (Britovsek et al., 1999). Crystallization from CH2Cl2—di­ethyl­ether at -20 °C afforded single crystals suitable for the crystallographic study.

Refinement top

All aromatic-H atoms were placed in geometrically idealized positions (C—H = 0.95 Å) and constrained to ride on their parent atoms with Uiso(H) = 1.2Ueq(C). The methyl-H atoms were located in SHELXL with an ideal geometry (C—H = 0.98 Å and Uiso(H) = 1.5Ueq(C)).

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.
