Abstract

The syntheses, crystal structures and characterization (IR, TGA/DSC) of the isostructural one-dimensional coordination polymers [Ce(C₇H₆NO₂)₃] _n (1) and [Pr(C₇H₆NO₂)₃] _n (2) are described. The metal ions adopt distorted capped square anti-prismatic MO₉ coordination geometries. The anthranilate ligands bridge the metal ions in bridging-bidentate (O, μ²-O′) mode to generate [010] chains in the crystal and each ligand features an intramolecular N-H⋯O hydrogen bond. It is notable that two very similar, but crystallographically distinct chains appear in the unit cell. Crystal data: 1, C₂₁H₁₈CeN₃O₆, M _r = 548.51, monoclinic, P2₁/c (No. 14), a = 25.0476(10) Å, b = 7.4924(2) Å, c = 24.6366(7) Å, β = 119.424(1)°, V = 4027.1(2) Å³, R(F) = 0.037, wR(F ²) = 0.068. 2, C₂₁H₁₈N₃O₆Pr, M _r = 549.29, monoclinic, P2₁/c (No. 14), a = 25.0077(13) Å, b = 7.4497(3) Å, c = 24.6063(12) Å, β = 119.392(2)°, V = 3994.1(3) Å³, R(F) = 0.031, wR(F ²) = 0.068.
