| Abstract: | Reaction of Sm(bpy)4 (bpy is 2,2′-bipyridyl) with di-tert-butyldiazabutadiene (dad) in tetrahydrofuran (THF) affords the mixed-ligand complex Sm(dad)2(bpy) (1). Complex1 was isolated as black paramagnetic crystals readily soluble in THF, 1,2-dimethoxyethane (DME), toluene, and ether. Compound1 was characterized by IR and ESR spectroscopy, X-ray diffraction analysis, and by the results of magnetic measurements. Based
on the difference between the Sm−N bond lengths and on the data of IR spectroscopy, the following formal charge distribution
in the molecule of complex1 was proposed: Sm3+(dad)2−(dad)1−(bpy)0.
