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.
