N,N′-Bis(5-bromo-2-hydroxy­benzyl­idene)-2,2-dimethylpropane-1,3-diamine

Abstract

The crystal structure of the title Schiff base compound, C19H20Br2N2O2, contains two crystallographically independent mol­ecules (A and B) in the asymmetric unit, with similar conformations. Intra­molecular O—H(...)N (× 4) and C—H(...)N (× 5) hydrogen bonds form six- and five-membered rings, producing S(6) and S(5) ring motifs, respectively. One of the N atoms in mol­ecule A acts as a trifurcated acceptor, the rest of the N atoms being bifurcated acceptors. The dihedral angles between the benzene rings in mol­ecules A and B are 47.83 (17) and 61.11 (17)°, respectively. The mol­ecular conformation is stabilized by intra­molecular O—H(...)N and C—H(...)N hydrogen bonds. The short distances between the centroids of the benzene rings [3.7799 (19)–3.890 (2) Å] indicate the existence of π–π inter­actions. In addition, the crystal structure is further stabilized by an inter­molecular C—H(...)O hydrogen bond, C—H(...)π inter­actions, and short inter­molecular Br(...)Br and Br(...)O contacts [3.4786 (5) and 3.149 (3) Å, respectively].

Comment

The condensation of primary amines with carbonyl compounds yields Schiff base (Casellato & Vigato, 1977) that are still now regarded as one of the most potential group of chelators for facile preparations of metallo-organic hybrid materials. In the past two decades, the synthesis, structure and properties of Schiff base complexes have stimulated much interest for their noteworthy contributions in single molecule-based magnetism, materials science, catalysis of many reactions like carbonylation, hydroformylation, reduction, oxidation, epoxidation and hydrolysis, etc. (Pal et al., 2005; Reglinski et al., 2004; Hou et al., 2001; Ren et al., 2002). Only a relatively small number of free Schiff base ligands have been characterized by X-ray crystallography (Calligaris & Randaccio, 1987). As an extension of our work (Fun, Kargar & Kia, 2008; Fun, Kia & Kargar, 2008; Fun, Mirkhani et al., 2008a,b) on the structural characterization of Schiff base compounds, the title compound (I), is reported here.

The crystal structure of the title compound (I) (Fig. I), contains two crystallographically independent molecules (A and B) in the asymmetric unit, with similar conformations. The bond lengths and angles are within normal ranges (Allen et al., 1987). Intramolecular O—H···N (x 4) and C—H···N (x 5) hydrogen bonds form six- and five-membered rings, producing S(6) and S(5) ring motifs, respectively (Bernstein et al. 1995) (Table 1). One of the nitrogen atoms in the molecule A acts as a trifurcated acceptor, but the rest of the nitrogen atoms are bifurcated acceptors. The dihedral angles between the benzene rings in molecule A and B is 47.83 (17)° and 61.11 (17)°. The molecular conformation is stabilized by intramolecular O—H···N and C—H···N hydrogen bonds. The short distances between the centroids of the benzene rings [Cg2–Cg2 = 3.7799 (19) Å and Cg3–Cg3 = 3.890 (2) Å] indicate the existence of π–π interactions. The Cg2 and Cg3 are the centroids of the C12A–C17A and C12B–C17B benzene rings. The interesting features of the crystal structure are short intermolecular Br···Br [symmetry code: 1/2 + x, -1/2 - y + 1/2 + z] and Br···O [symmetry code: -x, 1 + y, 1/2 - z] interactions, with distances of 3.4786 (5) and 3.149 (3) Å, respectively, which are significantly shorter than the sum of the van der Waals radii of the relevent atoms.

In addition, the crystal structure is further stabilized by intermolecular C—H···O hydrogen bond and C—H···π interactions.

Experimental

The synthetic method has been described earlier (Reglinski et al., 2004). Single crystals suitable for X-ray diffraction were obtained by evaporation of an ethanol solution at room temperature.

Refinement

H atoms bound to the O1A, O2A, and O2B were located in a difference Fourier map and refined freely. H atom bound to O1B was located from a difference Fourier map and constrained to refine with the parent atom after distance restraint of 0.84 (1) Å. The rest of the H atoms were positioned geometrically (C—H = 0.95–0.99 Å) and refined using a riding model.

Special details

Experimental. The low-temperature data was collected with the Oxford Cyrosystem Cobra low-temperature attachment.
Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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.
