The crystal complex Eu2 (3,4-DMBA) 6 (PHEN) 2 formed by europium (Ⅲ) and 3,4-dimethylbenzoic acid (3,4-HDMBA) and phenanthroline (PHEN) was synthesized. Its molecular weight is M = 1559.35. The crystal belongs to the triclinic system. The space group P1 has a = 1.2665 (4) nm, b = 1.3567 (4) nm and c = 1.0755 α = 98.87 (3) °, β = 108.25 (3) °, γ = 87.98 (2) °, Z = 1 and the final deviation factor R = 0.031. Eu (Ⅲ) ions were used as fluorescent probes to determine the high resolution spectra (HRS) of the complexes at 77K. The results of excitation, luminescence, time-resolved spectroscopy and luminescence lifetime of the europium complex show that there are two kinds of Eu (Ⅲ) ion sites with different chemical environments
