Source of material

All hydrogen atoms were placed in calculated positions and refined using a riding model. Aromatic C—H distances were set to 0.93 Å and their Uiso set to 1.2 times the Ueq of the parent atom.

Experimental details

All commercially available reagents were used as supplied. A mixture of 3-bromo-5-chlorosalicylaldehyde 0.471 g (1.0 mmol) and (±)-1.2-cyclohexanediamin 0.10 mL was dissolved in 20 mL of methanol and stirred for 30 min at room temperature. The yellow suspension was then refluxed at 60 °C for 3 h and filtrated. The colorless crystals of the title compound slowly appears after one week.

Comment

Because of the special coordination ability, flexible spatial and electronic effects, halogenated Schiff-base ligand have attracted more and more attention in coordination chemistry [5], [6], [7], [8], [9], [10]. In order to explore the relationship between molecular structure and physicochemical properties of Schiff-base compound, we report a new salen-type Schiff base.

The title compound crystallizes in the space group P21/c, thus the unit cell contains two pairs of racemic molecules, and overall exhibiting centrosymmetric configuration. The bond lengths and angles are within the normal ranges and are closed to the related structures [11].

There are two strong intramolecular O—H⋯N hydrogen bonds between the hydroxyl group and the nitrogen atom, with the distance of O(1)–H(1)⋯N(1) and O(2)–H(2)⋯N(2) are 1.8310(3) and 1.8714(3) Å, respectively. Further intermolecular C—H⋯π hydrogen bonds and aromatic face-to-face π-π interactions play important roles for the crystal packing. [Interactions: C(11)—H(11B)⋯Cg(1) with distance = 3.662(4) Å; Cg1⋯Cg1 (1 − X, −Y, −Z) and Cg3⋯Cg3 (1 − X, −Y, 1 − Z). Centroid-to-centroid distance = 3.638(2) and 3.586(2) Å, respectively, where Cg1 is the centroid of the C1—C6 ring and Cg3 is the centroid of the C15—C20 ring.]
