Tetra­aqua­bis­(2,6-dihy­droxy­benzoato-κO (1))(2,6-dihy­droxy­benzoato-κ(2) O (1),O (1′))gadolinium(III) dihydrate

In the title compound, [Gd(C(7)H(5)O(4))(3)(H(2)O)(4)]·2H(2)O, the Gd(III) ion shows a distorted square anti­prismatic coordination formed by four aqua ligands and four O atoms from the three 2,6-dihy­droxy­benzoate (L) ligands. Two L ligands coordinate the Gd(III) ion in a monodentate mode, while the third coordinates it in a bidentate–chelating coordination mode. An extensive three-dimensional O—H⋯O hydrogen-bonding network consolidates the crystal packing.
