In the mol­ecule of the title compound, C28H40N2O2, the tert-butyl group is disordered over two positions; site-occupation factors were kept fixed at 0.5. The morpholine ring has a chair conformation. Intra­molecular O—H⋯N hydrogen bonding results in the formation of a planar six-membered ring, which is oriented at a dihedral angle of 0.70 (3)° with respect to the adjacent aromatic ring. The dihedral angle between the benzene rings is 67.66 (3)°.

Comment top

The simple and readily accessible salicylaldiminato ligand family has played an important role in the development of transition metal coordination chemistry, and recently they have been shown to support highly active polymerization centers for both the early and late transition metals (Younkin et al., 2000). Increasing the sizes of the imino and the o-phenoxy substituents has a pronounced effect on the activity of the catalyst and the molecular weight of the polymer (Gibson & Spitzmesser, 2003). We have recently prepared the novel title ligand, (I), and report herein its crystal structure

In the molecule of the title compound, (I), (Fig. 1) the bond lengths and angles are within normal ranges. When the crystal structure was solved, the three methyl groups of tert-butyl bonded to the phenoxy ring were found to be disordered.

Ring A (O1/N1/C1—C4) is not planar, having total puckering amplitude, QT, of 1.022 (3) Å. It adopts chair [ϕ = 29.58 (2)° and θ = 56.99 (3)°] conformation (Cremer & Pople, 1975). The intramolecular O—H···N hydrogen bond (Table 1) results in the formation of a planar six-membered ring C (O2/H2/N2/C7/C8/C16), which is oriented with respect to rings B (C6—C11) and D (C17—C22) at dihedral angles of B/C = 0.70 (3)° and C/D = 67.93 (4)°. So, rings B and C are also nearly coplanar. The dihedral angle between rings B and D is B/D = 67.66 (3)°.

Experimental top

2,6-Diisopropylaniline (3.94 g, 22.2 mmol) was added via syringe to a solution of 5-tert-butyl-2-hydroxy-3-(morpholinomethyl)benzaldehyde (6.15 g, 22.2 mmol) in EtOH (100 ml). The solution was refluxed for 12 h, and then dried over magnesium sulfate, filtered and the volatiles were removed under reduced pressure. Extraction into pentane (10 ml) was followed by cooling to 243 K afforded yellow crystals of (I) (yield; 70%). Spectroscopic analysis: IR (KBr, ν, cm-1): 3055.8, 3027.2, 2961.6, 2864.9, 1618.8, 1584.9, 1468.4, 1358.9, 1276.7, 1119.2, 865.7; 1H NMR (CDCl3, δ, p.p.m.): 1.291 (d, J=6.5 Hz, 12H), 1.355 (s, 9H), 2.619 (s, 4H), 2.933–2.995 (m, 2H), 3.672 (s, 2H), 3.792–3.810 (t, 4H), 7.204(s, 3H), 7.320–7.325 (d, J=2.5 Hz, 1H), 7.539–7.534 (d, J=2.5 Hz, 1H), 8.278 (s, 1H), 9.83(s, 1H)

Refinement top

When the crystal structure was solved, the three methyl groups of tert-butyl bonded to the phenoxy ring were found to be disordered. They were each modelled with disorder over two positions with a common carbon atom and occupancies of 50:50. H atoms were positioned geometrically, with O—H = 0.82 Å (for OH) and C—H = 0.93, 0.98, 0.97 and 0.96 Å for aromatic, methine, methylene and methyl H, respectively, and constrained to ride on their parent atoms with Uiso(H) = xUeq(C,O), where x = 1.5 for OH and methyl H and x = 1.2 for all other H atoms.

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.
