Syntheses, crystal structures, magnetic properties of two new lanthanide-nitronyl nitroxide complexes (LnШ = GdШ, NdШ)

► Synthesize two rare-earth metal complexes based on nitronyl nitroxide radicals. ► Two Lanthanide(III) complexes have eight-coordinated dodecahedral geometry. ► Weak ferromagnetic coupling exists between Gd(III) ion and radical. ► Weak antiferromagnetic interaction exists between the Nd(III) ion and radical.
