Key indicators: single-crystal X-ray study; T = 200 K; mean (C-C) = 0.002 Å; R factor = 0.032; wR factor = 0.086; data-to-parameter ratio = 13.9.In the crystal structure of the title compound, [Mg(H 2 O) 6 ]-(C 7 H 5 O 6 S) 2 Á2H 2 O, the octahedral complex cation lies on an inversion centre and is hydrogen bonded through the coordinated water molecules to the substituted benzenesulfonate monoanions and the water molecules of solvation. These interactions together with a carboxylic acid O-HÁ Á ÁO(sulfonate) association give a three-dimensional structure. Related literature

Hexaaquanickel(II) bis(3-carboxy-4-hydroxybenzenesulfonate) dihydrate, [Ni(H2O)6][C6H3(CO2H)(OH)SO3]2·2H2O, (I), crystallizes in the triclinic space group P\overline{1} with the nickel(II) aqua complexes on centers of inversion. The carboxylate group is protonated and neither it nor the sulfonate group is involved in direct coordination to the metal ions. The structure consists of alternating layers of inorganic cations and organic anions linked by O—H...O hydrogen bonds that also include non-coordinated water molecules of crystallization. The first-row divalent transition-metal salts of this anion are reported as both dihydrates and tetrahydrates, with two distinct structures for the dihydrates that are both layered but differ in the hydrogen-bonding pattern. Compound (I) represents the second known example of one of these structures. Hexaaquacobalt(II) bis(3-carboxybenzenesulfonate) dihydrate, [Co(H2O)6][C6H4(CO2H)SO3]2·2H2O, (II), also crystallizes in triclinic P\overline{1} with the cobalt(II) aqua complexes on centers of inversion. The structure is also built of alternating layers of complex cations and organic anions without direct coordination to the metal by the protonated carboxylate or unprotonated sulfonate groups. A robust O—H...O hydrogen-bonding network involving primarily the coordinated and non-coordinated water molecules and sulfonate groups directs the packing. This is the first reported example of a divalent transition-metal salt of the 3-carboxybenzenesulfonate anion.
