catena-Poly[[(1,10-phenanthroline-κ(2) N,N′)lanthanum(III)]-μ-(5-bromo-2-hy­droxy­benzoato)-κ(2) O (1):O (1′)-di-μ-chlorido]

In the title complex, [La(C(7)H(4)BrO(3))Cl(2)(C(12)H(8)N(2))](n), the La(III) ion is eight-coordinated by two carboxyl­ate O atoms from two 5-bromo­salicylate ligands, two N atoms from a chelating 1,10-phenanthroline ligand and four bridging Cl atoms in a distorted square-anti­prismatic geometry. The La(III) ions are linked by bridging carboxyl­ate groups and chloride anions into a chain along [100]. An intra­molecular O—H⋯O hydrogen bond is formed in the 5-bromo­salicylate ligand. π–π inter­actions between the pyridine and benzene rings and between the benzene rings are observed [centroid–centroid distances = 3.794 (5) and 3.804 (4) Å].
