Hexa­aqua­manganese(II) bis­[5-(4-cyano­phenyl)-2H-tetrazolate]

The reaction of terephthalo­nitrile and sodium azide catalyzed by manganese chloride tetrahydrate converts one nitrile group to tetrazole and leaves the other nitrile group unchanged. The Mn^II atom in the title compound, [Mn(H₂O)₆](C₈H₄N₅)₂, is coordinated by six water mol­ecules and lies on a position of 2/m crystallographic symmetry. The plane of the tetrazolate anion is perpendicular to a crystallographic mirror plane.
