Rare-earth tris-diketonato [RE(dike)3 pyterpy] metalloligands can be prepared reacting at room temperature [RE(dike)3 dme] (dme = 1,2-dimethoxyethane; dike = tta with Htta = 2-thenoyltrifluoroacetone and RE = La, 1 ; Y, 2 ; Eu, 3 ; Dy, 4 ; or dike = hfac with Hhfac hexafluoroacetylacetone, and RE = Eu, 5 ; Tb, 6 ; Yb 7 ) with 4'-(4‴-pyridil)-2,2':6',2″-terpyridine (pyterpy). The molecular structures of 1 , 5 , 6 , and 7 have been studied through single-crystal X-ray diffraction showing mononuclear neutral complexes with the rare-earth ion in coordination number nine and with a muffin-like coordination geometry...
