Green synthesis and crystal structure of 3-(benzothiazol-2-yl)thiophene

چکیده
The title compound, C11H7NS2, was prepared in high yield (87%) using a solvent-free microwave-assisted synthesis. The structure shows whole-mol-ecule disorder with occupancies for two orientations (A and B) of 0.4884 (10) and 0.5116 (10), respectively. The thio-phene and benzo-thia-zole rings are almost planar and make dihedral angles of 10.02 (18) and 12.54 (19)° for orientations A and B, respectively. Slipped π-π stacking between the aromatic rings, together with C-H⋯π, C-H⋯S and C-H⋯N inter-actions, result in a herringbone motif in the crystal packing.

The title complex, [Cu(2)(C(15)H(12)N(3)O(2)S)(2)(NO(3))(CH(3)OH)]NO(3), has two Cu(II) centres coordinated by two deprotonated 2-[(benzothia-zol-2-yl)hydrazonometh-yl]-6-methoxy-phenol ligands, a methanol mol-ecule and a nitrate ion. Both Cu(II) centres are penta-coordinated in a distorted square-pyramidal fashion. The crystal structure is stabilized by N-H⋯O and O-H⋯O hydrogen bonds.
