title: Tetra-kis(μ-3-aza-niumylbenzoato)-κO:O,O';κO,O':O;κO:O'-bis-[triaqua-chloridolanthanum(III)] tetra-chloride dihydrate.
abstract: The tiltle complex, [La(2)(C(7)H(7)NO(2))(4)Cl(2)(H(2)O)(6)]Cl(4)·2H(2)O, is a centrosymmetric dimer formed by edge-sharing LaO(5)(H(2)O)(3)Cl polyhedra linked together by a carboxyl-ate ligand. The two La(III) metal ions are linked by two bidentate bridging carboxyl-ate groups with a κ(2)O:O' coordination mode and two bidentate chelating bridging carboxyl-ate groups with a κ(3)O:O,O' coordination mode. The coordination sphere of lanthanum, completed by a terminal chloride and three water mol-ecules, adopts a distorted tricapped trigonal-prismatic arrangement. N-H⋯Cl, N-H⋯O and O-H(water)⋯Cl hydrogen bonds, and slipped π-π inter-actions between parallel benzene rings [centroid-centroid distance of 3.647 (3) Å] are observed in the structure. These combine to stabilize a three-dimensional network.
