Two new ternary complexes La(Ala)3Im(ClO4)3•3H2O (La1) and La(Ala)3BenIm(ClO4)3•H2O (La2) of lanthanum perchlorate and DL-α-alanine (Ala),imidazole (Im) or benzimidazole (BenIm) have been synthesized.In methanol, the composition of the complexes is determined by EDTA capacity analysis and elemental analysis. The characters and thermostability have been studied by IR, UV, X-ray, and TG-DTG, DSC analysis. Bioactivity experiments show that the complexes have bacteriostasis effect for five variety of microbe.
