New heterodinuclear pivalates (HPiv)(6)EuTb(Piv)(6) (5) and (Phen)(2)EuTb(Piv)(6) (6), where Piv = (CH3)(3)CCO2-, 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.
