The asymmetric unit of the title coordination polymer, {[Mn(C6Cl2O4)(C10H8N2)]·2C2H5OH}n, consists of one MnIIion, one 2,2′-bipyridine (bpy) ligand, one chloranilate (CA2−) ligand and two ethanol solvent molecules. The MnIIion is octahedrally coordinated by two N atoms of one bpy ligand and four O atoms of two chloranilate ions. The chloranilate ion serves as a bridging ligand between the MnIIions, leading to an infinite zigzag chain along [101]. π–π stacking interactions [centroid–centroid distance = 4.098 (2) Å] is observed between the pyridine rings of adjacent chains. The ethanol molecules act as accepters as well as donors for O—H...O hydrogen bonds, and form a hydrogen-bonded chain along theaaxis. The H atoms of the hydroxy groups of the two independent ethanol molecules are each disordered over two sites with equal occupancies.
