Key Points

This research aims to explore the coordination capabilities of ortho-aryl phosphine oxides with lanthanoid metals.
Synthesize tetranuclear lanthanoid complexes using tris(5-tert-butyl-2-hydroxyphenyl)-phosphine oxide ligands.
Characterize the synthesized complexes through various analysis techniques.
Investigate the magnetic behaviour of the resulting complexes.
Successfully synthesized three distinct tetranuclear lanthanoid complexes.
Characterization reveals interaction between hydroxide and phosphine oxide ligands.
Magnetic behavior suggests potential applications in advanced materials.

Implication

Synthesis and characterisation of lanthanoid complexes shows magnetic behaviour implications in materials science.

Abstract

Functionalised ortho-aryl phosphine oxides are assessed as candidates for lanthanoid (Ln) coordination. The series of tetranuclear Ln complexes synthesised [{Ho(μ3-OH)(μ2,κ3-LH)(C2H5OH)}4] (1), [{Dy(μ3-OH)(μ2,κ3-LH)(C2H5OH)}3{Dy(μ3-OH)((μ2,κ3-LH)(H2O)}]·5(EtOH) (2) and [{Tb(μ3-OH)(μ2,κ3-LH)(C2H5OH)}4]·4.8(EtOH) (3) with ligand tris(5-tert-butyl-2-hydroxyphenyl)-phosphine oxide...
