Bis(ethyl­enediamine-κ2N,N′)(2-oxido-5-sulfonatobenzoato-κ2O1,O2)chromium(III) dihydrate

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) A] from two ethyl­enediamine mol­ecules, one phenolate O atom [Cr—O = 1.899 (4) A] and a carboxyl­ate O atom [Cr—O = 1.929 (4) A] 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.
