title: Tetra-aqua-bis-(2,6-dihy-droxy-benzoato-κO)(2,6-dihy-droxy-benzoato-κO,O)gadolinium(III) dihydrate.
abstract: 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 anti-prismatic coordination formed by four aqua ligands and four O atoms from the three 2,6-dihy-droxy-benzoate (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.
