Synthesis and Characterisation of Rare Earth Complexes Supported by para‐Substituted Cinnamate Ligands

This is the authors' abstract. We don't add key points for this paper.

The preparations and characterisations of a range of lanthanoid 4‐(R)‐substituted (4‐Rcinn, R = OH, OMe, NO2, Cl), known to have good anticorrosion properties, are reported. The crystal structure of [Ce(4‐OHcinn)3(MeOH)2(H2O)]·MeOH is a polymer, in which the cerium atoms are nonacoordinate, and adjacent cerium atoms are bridged by either two bridging bidentate or two bridging tridentate carboxylate ligands. Each cerium atom also has one monodentate 4‐hydroxycinnamate ligand, one aqua ligand, and two methanol ligands.
