Abstract: The asymmetric unit of the title coordination polymer, {[Mn(C₆Cl₂O₄)(C₁₀H₈N₂)]·2C₂H₅OH}_n, consists of one Mn^II ion, one 2,2'-bipyridine (bpy) ligand, one chloranilate (CA^2-) ligand and two ethanol solvent molecules. The Mn^II ion 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 Mn^II ions, leading to an infinite zigzag chain along [101]. - 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-HO hydrogen bonds, and form a hydrogen-bonded chain along the a axis. The H atoms of the hydroxy groups of the two independent ethanol molecules are each disordered over two sites with equal occupancies.
