title: catena-Poly[4,4'-bipyridinium [[cis-dichloromanganese(II)]-di-mu-chloro]], a novel manganese(II) coordination polymer with 4,4'-bipyridinium.
abstract: The title novel manganese(II) coordination polymer, {(C10H10N2)[MnCl4]}n, consists of a one-dimensional infinite zigzag chain composed of polymeric [MnCl4]2- units in which each Mn2+ ion is located on a twofold rotation axis and is coordinated to two terminal Cl atoms and four bridging chloro ligands. Adjacent Mn2+ ions are linked by double Cl bridges arranged about a centre of inversion, thus forming anionic chains of distorted edge-sharing octahedra. Rows of approximately parallel 4,4'-bipyridinium cations run side-by-side with the MnCl4 chains. A two-dimensional layer structure is constructed via hydrogen bonds and by additional pi-pi stacking interactions.
