Bis(2-amino-3H-benzothia­zolium) bis­(7-oxabicyclo­[2.2.1]heptane-2,3-di­carbox­yl­ato)manganate(II) hexa­hydrate

In the crystal structure of the title salt, (C(7)H(7)N(2)S)(2)[Mn(C(8)H(8)O(5))(2)]·6H(2)O, the heterocyclic N atom of the 2-amino­benzothia­zole mol­ecule is protonated. The Mn(II) atom (site symmetry [Image: see text]) has a slightly distorted octa­hedral MnO(6) coordination defined by the bridging O atoms of the bicyclo­heptane unit and four carboxyl­ate O atoms of two symmetry-related and fully deprotonated ligands. The crystal packing is stabilized by N—H⋯O hydrogen bonds between the cations and anions and by O—H⋯O hydrogen bonds including the crystal water mol­ecules.
