The title compound, [MnCl2(C10H8N2)]n, crystallizes with a two-dimensional network constructed from linear chains of edge-sharing MnCl4 square-planar units cross-linked by bidentate 4,4'-bi­pyridine bridges. The Mn atom and the bipyridine moieties lie on sites with 222 crystallographic symmetry; the Cl atom lies on a twofold axis. The bi­pyridine mol­ecule is twisted about the central C-C bond by 33.5 (3)°.

Refinement. The structure was solved by direct methods and all non-H atoms were located. H atoms were subsequently located in difference Fourier maps and their coordinates and isotropic displacements parameters refined.
