In the title compound, [ZnCl2(C7H6N2S)2]·0.5CH3CH2OH, the ZnII atom is coordinated by two N atoms of two 2-aminobenzothiazole ligands and two Cl atoms within a distorted tetrahedral geometry. The dihedral angle between the N/Zn/N and Cl/Zn/Cl planes is 86.22 (7)°. The benzothiazole molecules are almost perpendicular to each other, forming a dihedral angle of 80.20 (8)°. The molecular structure is stabilized by intramolecular N—H⋯Cl hydrogen bonds. In the crystal, intermolecular N—H⋯Cl hydrogen bonds link the molecules into a three-dimensional network. The SQUEEZE procedure in PLATON [Spek (2009 ▶). Acta Cryst. D65, 148–155] was used to model a disordered ethanol solvent molecule; the calculated unit-cell data allow for the presence of half of this molecule in the asymmetric unit.
