In the title complex, [Cu(C13H8NOS)2], the CuII atom is coordinated by two N atoms and two O atoms from two bidentate benzothiazolphenolate ligands, forming a distorted tetrahedral geometry [dihedral angle between two N—Cu—O planes: 45.1 (2)°]. The dihedral angles between the benzothiazole ring systems and the phenol rings are 4.1 (4) and 5.8 (4)°, indicating an almost planar geometry. Weak intra- and intermolecular C—H⋯O hydrogen bonds are observed. In the crystal, weak π–π interactions between aromatic and thiazole rings [centroid–centroid distances = 3.626 (3) and 3.873 (3) Å] link the molecules into a two-dimensional supramolecular network along the bc plane.
Keywords: crystal structure; Cu(II) complex; benzothiazolphenol; hydrogen bonding; π–π interactions.

To a solution of 2-(2-hydroxyphenyl)benzothiazole (0.227 g, 1.0 mmol) in EtOH (15 ml) was added a 1N NaOH solution slowly until pH = 8 at room temperature. After 6 h of stirring, a solution of Cu(NO3)2.3H2O (0.121g, 0.50 mmol) in EtOH (15 ml) was added. After 24 h of stirring at room temperature, the product was isolated as a dark green powder by removing the solvent. Green single crystals of the title complex were obtained by slow evaporation of its concentrated solution in dichloromethane at room temperature.

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. |
