  Abstract: A series of new dimeric complexes with   composition [Ln(2)(hfa)(6)(4-cpyNO)(3)](2:3 adduct,   Ln=Sm-III-Dy-III, Tm-III) were synthesized and fully   characterized. X-ray diffraction data of   [Tb-2(hfa)(6)(4-cpyNO)(3)]center dot CHCl3 confirmed the dimeric   structure; Tb ions are nine-coordinated by six O atoms from three   hfa-ligands and three O atoms from three bridging 4-cpyNO   molecules. The photophysical properties (absolute quantum yields   and luminescence lifetimes) of the Eu-III and Tb-III 2:3 adducts   are presented and compared with those of the 2:2 adducts.
