New solid ternary complexes of rare earth with L-Phenylalanine (L-Phe) and o-Phenanthroline (Phen) were synthesized in ethyl alcohol solution. Their composition were characterized by elemental analysis, molar conductance, IR, Raman, UV-VIS, TG-DTA. The compositions of the complexes were confirmed to be RE(Phe)_3Phen Cl_3·3H_2O(RE=La 3+, Ce 3+, Pr 3+, Nd 3+, Sm 3+, Eu 3+, Er 3+, Y 3+). The antibacterial activities testing indicates that all these solid ternary complexes have antibacterial ability against Escherich coli, Staphy lococcus aureus, Candida albican (MIC are about 65×10 -4%, 15×10 -3%, 4×10 -2%, respectively).
They are synthesized synthetically in elemental analysis, molar conductance, IR, Raman, UV-VIS, TG -DTA. The compositions of the complexes were confirmed to be RE (Phe) _3Phen Cl_3 · 3H_2O (RE = La 3+, Ce 3+, Pr 3+, Nd 3+, Sm 3+, Eu 3+, Er 3+ , Y 3+). The antibacterial activities testing said that all these solid ternary complexes have antibacterial ability against Escherich coli, Staphy lococcus aureus, Candida albican (MIC are about 65 × 10 -4%, 15 × 10 -3%, 4 × 10 -2%, respectively).
