Abstract top

The title compound, C22H26N2O2, is chiral; the absolute configuration follows from the known chirality of the input reagents. The asymmetric unit contains two crystallographically independent molecules in different orientations. The two molecules are related to each other by a non-crystallographic twofold rotation axis, while each molecule exhibits a further pseudo-twofold axis. Bond distances and angles are similar in the two molecules. Intermolecular C-H...[pi](ring) interactions and intramolecular O-H...N hydrogen bonds are observed in the crystal structure.

Comment top

The existence of a chiral centre in an organic ligand is very important for the construction of noncentrosymmetric or chiral coordination polymers that exhibit desirable physical properties such as ferroelectric behavior (Qu et al., 2004). As a part of our ongoing investigations in this field we have determined the crystal structure of the title compound, (I).

Fig. 1 shows the asymmetric unit consisting of two molecules of (I). The two crystallographically independent molecules have the same geometrical parameters within the precision of the experiments. The bond lengths and angles in (I) are comparable to the corresponding values in the related structures, tris[(5-bromosalicylidene)aminoethyl]amine (Figuet et al., 2001), N,N'-bis(salicylidene)-1,4-butanediamine (Kennedy & Reglinski, 2001) and N-(4-Butylphenyl)salicylaldimine (Thamotharan et al., 2003). The average for the N1—C1—C6—N2 and N3—C28—C23—N4 torsion angles is 67.5 (3)°, the average dihedral angle between two benzene rings within one molecule is 48.0 (1)°, and the average distance between the centers of the two benzene rings is 6.53 Å. Like other Schiff base compounds containing salicylidene (Figuet et al., 2001; Kennedy & Reglinski, 2001; Thamotharan et al., 2003) the hydroxyl groups form intramolecular hydrogen bonds with the N atoms (Table 2), thereby completing six-membered rings.

Experimental top

o-Hydroxyacetophenone (0.68 g, 5.0 mmol) and (1R,2R)-(-)-diaminocyclohexane (0.30 g, 2.6 mmol) were dissolved in ethanol (30 mL), and heated to reflux for 8 h until the raw material disappeared according to TLC detection. The solution was cooled to room temperature, then solvent was removed under reduced pressure. The residue was recrystallized with iso-propanol to afford yellow crystals, some of which were suitable for X-ray analysis.

Refinement top

Positional parameters of the H atoms bonded to C atoms were calculated geometrically and were allowed to ride on the C atoms with Cmethine—Hmethine = 0.97; Cmethylene—Hmethylene = 0.96; Caryl—Haryl=0.93 Å; UisoH = 1.2 UeqC. Positional parameters of the H atoms bonded to O atoms were calculated geometrically with the C—O—H angle tetrahedtral and refined in a rotating mode with O—H = 0.82 Å and UisoH = 1.5 UeqO. In the absence of significant anomalous scattering effects, 4211 Friedel pairs were merged.

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.
