title: cyclo-Tetra-kis(μ-naphthalene-1,8-dicarboxyl-ato)tetra-kis-[diaqua-(2,2'-bipyridine)-manganese(II)] tetra-hydrate.
abstract: In the title centrosymmetric tetra-nuclear complex, [Mn(4)(C(12)H(6)O(4))(4)(C(10)H(8)N(2))(4)(H(2)O)(8)]·4H(2)O, two independent Mn(II) ions are coordinated in a slightly disorted octa-hedral environment by two aqua ligands, two naphthalene-1,8-dicarboxyl-ate (1,8-nap) ligands and one bis-chelating 2,2'-bipyridine (2,2'-bipy) ligand. In the crystal, mol-ecules are linked by inter-molecular O-H⋯O hydrogen bonds into chains along [100]. These chains are further linked by weak π-π inter-actions with centroid-centroid distances in the range of 3.609 (2)-3.758 (1) Å, forming a three-dimensional supra-molecular network.
