Coordination compounds of europium(III), terbium(III), samarium(III) acetates with 1,10-phenanthroline (phen) and 5-phenyltetrazole (HL) are synthesized. By the single crystal X-ray diffraction (XRD) analysis of the samarium(III) complex the compound is found to be binuclear with formula [Sm2(phen)2(CH3COO)6]·2HL. By the powder XRD analysis of polycrystalline samples all obtained complexes are found to be isostructural. A change in the synthesis procedure of the europium(III) acetate–phen–HL system leads to the formation of [Eu(phen)2(H2O)3(CH3COO)]L2·6H2O single crystals. The photoluminescent properties of the polycrystalline compounds are studied: emission and excitation spectra are recorded and the quantum yield is calculated. The HL quantum yield is 33% while it is 36% and 22% for the obtained complexes of europium(III) and terbium(III) respectively. The excited state lifetime is also determined for lanthanide(III) complexes: 1.6 ms for europium(III) and 0.6 ms for terbium(III).
