Catena-Poly[[[bis-(1,10-phenanthroline-?N,N')manganese(II)]-?-9,10-dioxo-anthracene-1,5-disulfonato-?O:O] tetra-hydrate].

ABSTRACT: The title complex, {[Mn(C(14)H(6)O(8)S(2))(C(12)H(8)N(2))(2)]·4H(2)O}(n), exhibits a chain-like polymeric structure with 9,10-dioxo-anthracene-1,5-disulfonate anions bridging Mn(II) atoms in a bis-monodentate mode. The unique Mn(II) atom is located on a crystallographic centre of inversion. Four N atoms from two chelating 1,10-phenanthroline ligands and two sulfonate O atoms from two symmetry-related 9,10-dioxoanthracene-1,5-disulfonate anions give rise to a slightly distorted octa-hedral coordination environment around the Mn(II) centre. The centroid of the central ring of the anthraquinone ligand represents another crystallographic centre of inversion. In the crystal structure, inter-ligand ?-? stacking [centroid-to-centroid distances 3.532?(1) and 3.497?(3)?Å] and inter-molecular O-H?O hydrogen-bonding inter-actions assemble the chains into a three-dimensional supra-molecular network.
