9-Amino-acridinium bis-(pyridine-2,6-dicarboxyl-ato-κ(3)O(2),N,O(6))ferrate(III) tetra-hydrate.
The asymmetric unit of the title compound, (C(13)H(11)N(2))[Fe(C(7)H(3)NO(4))(2)]·4H(2)O, contains a 9-amino-acridinium cation, one anionic complex and four uncoordinated water mol-ecules. In the anionic complex, the Fe(III) ion is six-coordinated by two almost perpendicular [dihedral angle = 88.78 (7)°] pyridine-2,6-dicarboxyl-ate ligands in a distorted octa-hedral geometry. In the crystal, anions are connected into chains along [10-1] by weak C-H⋯O inter-actions, which create ten-membered hydrogen-bonded R(2) (2)(10) rings. These chains are linked by three-membered water clusters. The final three-dimensional network is constructed by numerous inter-molecular O-H⋯O and N-H⋯O inter-actions.
