Abstract: New heterodinuclear pivalates (HPiv)6EuTb(Piv)6 (5) and (Phen)2EuTb(Piv)6 (6), where Piv=(CH3)3CCO2 −, the 2,2-dimethylpropanoate anion, and Phen=1,10-phenanthroline, were synthesized. The structures and compositions of the heterodinuclear molecules were determined by X-ray diffraction and based on magnetic measurements, inductively coupled plasma atomic emission spectrometry (ICP-AES) and the results of the research on the thermal decomposition and vaporization of the complexes. Under UV excitation, complex 6 exhibits luminescence and complete intramolecular excitation energy transfer to the Eu3+ ions involving singlet levels of the Phen ligand and f–f levels of the Tb3+ ions.
