A homobimetallic complex, [{Sm(tta)3(MeOH)}2(μ-bpm)]*1 bpm (tta = 2-thenoyltrifluoroacetonato, bpm = 2,2′-bipyrimidine) has been synthesized and structurally characterized by single-crystal X-ray diffraction. Magnetic measurements (between 5 and 295 K) show that the two metal centers bridged by the bpm connector are magnetically almost isolated. The SmIII emission is observed upon excitation in a wide range of wavelengths going from the UV to the visible (250-500 nm).
