Abstract: In the title compound, [Cr(C₇H₃O₆S)(C₂H₈N₂)₂]·2H₂O, the chromium(III) ion is at the centre of a compressed octahedron formed by four N atoms [Cr-N = 2.060 (5)-2.107 (5) Å] from two ethylenediamine molecules, one phenolate O atom [Cr-O = 1.899 (4) Å] and a carboxylate O atom [Cr-O = 1.929 (4) Å] from the 2-oxido-5-sulfonatobenzoate ligand. These two O atoms and two of the N atoms occupy the equatorial positions and the remaining N atoms occupy the axial positions. The crystal structure is stabilized by a number of intermolecular hydrogen bonds.
