Eight-coordinate mono- and dinuclear Dy(iii) complexes containing a rigid equatorial plane and an anisobidentate carboxylate ligand in the axial position: synthesis, structure and magnetism

Abstract

Octacoordinate mononuclear Dy(iii) complexes, [Dy(LN3O2Ph)(Ph3PO)(OOCR)] (where R = C6H5 (1), C(CH3)3 (2), CF3 (3)) and a dinuclear complex, [Dy2(LN3O2Ph)2(Ph3PO)2{(OOC)2C6H4}] (4) were synthesized. Complexes 1 and 4 showed SMM behaviour.
