摘要
The title compound, [Mn(C7H4O5S)(C12H8N2)(2)(H2O)](.)4H(2)O, which was obtained by the reaction of MnCl2 with sodium hydrogen 3-sulfobenzoate and 1,10-phenanthroline, is a monomer. The coordination polyhedron of the Mn atom is a distorted octahedron. pi-pi Interactions between neighboring monomers and extensive hydrogen bonding consolidate the stability of the crystal structure.
