A new two-dimensional (2D) coordination polymer (CP) [La(C 18 H 14 N 3 O 6 ) 2 (H 2 O)(OH)] n has been prepared from a 1,2,3-triazole linker and lanthanum nitrate hexahydrate in DMF. The La-CP was characterized by single-crystal X-ray crystallography, highlighting the binding motif at La ions and the fact that the material contains channels with entrapped solvent. The CP showed good catalytic activity for the oxidation of a wide variety of olefins (linear, cyclic, aromatic, and functionalized alkenes) to aldehydes. Mechanistic studies show that the oxidation reaction proceeds via a non-free-radical mechanism. The catalyst could be recovered and reused five times without major changes in activity for the oxidation of styrene to benzaldehyde.
