Abstract: This study explores crystal engineering strategies for rare earth heteroleptic complexes, focusing on ligand design, supramolecular control, and functional performance. Phosphine oxide ligands (TPPO) synergize steric/electronic effects to stabilize coordination geometries, while mixed-ligand systems (e.g., TPPO/phen) enhance Eu3+ luminescence (26.88% quantum yield). Polyoxometalates (POMs) template 3D architectures via hydrogen/charge interactions, enabling >95% photocatalytic dye degradation and >200 °C thermal stability. Rare earth-transition metal systems integrate 2D/3D topologies and multifunctionality (luminescence, gas adsorption) through electronic coupling. Additionally, carbon-based oxygen ligand systems (e.g., β-diketonates) demonstrate the applicability of these core strategies—leveraging synergistic N-donor coordination and supramolecular interactions to achieve advanced functionalities like temperature-responsive luminescence. Future work will prioritize flexible ligand engineering and stimuli-responsive designs for applications in clean energy and quantum technologies, establishing a roadmap for advanced rare earth materials.
