catena-Poly[[[bis­(2,2′-bipyridine)manganese(II)]-μ(4)-3,3′-sulfanediyldipropionato] bis­(perchlorate)]

The title compound, [Mn(2)(C(6)H(8)O(4)S)(C(10)H(8)N(2))(4)](ClO(4))(2), which was crystallized from an aqueous solution, features two Mn(II) atoms in the asymmetric unit, each being coordinated by four N-atom donors from 2,2′-bipyridine ligands and two O atoms of two different 3,3′-sulfanediyldipropionate (L) ligands, with the O atoms in cis positions. The two carboxyl­ate groups of each L ligand, which adopt a syn-anti coordination mode, combine with four Mn(II) atoms, yielding one-dimensional chains extending along [010].
