title: catena-Poly[[[(2,2'-bipyridine-κ(2)N,N')manganese(II)]-μ-(2,5-dichloro-3,6-dioxocyclo-hexa-1,4-diene-1,4-diolato)-κ(4)O(1),O(6):O(3),O(4)] ethanol disolvate].
abstract: The asymmetric unit of the title coordination polymer, {[Mn(C(6)Cl(2)O(4))(C(10)H(8)N(2))]·2C(2)H(5)OH}(n), consists of one Mn(II) ion, one 2,2'-bipyridine (bpy) ligand, one chloranilate (CA(2-)) ligand and two ethanol solvent mol-ecules. The Mn(II) ion is octa-hedrally 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]. π-π stacking inter-actions [centroid-centroid distance = 4.098 (2) Å] is observed between the pyridine rings of adjacent chains. The ethanol mol-ecules act as accepters as well as donors for O-H⋯O hydrogen bonds, and form a hydrogen-bonded chain along the a axis. The H atoms of the hy-droxy groups of the two independent ethanol mol-ecules are each disordered over two sites with equal occupancies.
