摘要
在甲醇介质中,用La(ClO4)3·nH2O与丙氨酸(CH3CHNH2COOH,简称Ala)及咪唑(C3H4N2,简称Im)或苯并咪唑(C7H6N2,简称BenIm)合成出两个新三元配合物La(Ala)3Im(ClO4)3·3H2O(简称La1)和La(Ala)3-BenIm(ClO4)3·H2O(简称La2).对配合物进行了容量分析及元素分析,确定了其组成.通过IR、UV、XRD及TG-DTG、DSC进一步研究了配合物的配位行为及热稳定性.生物活性试验表明该类配合物对5种菌均具有不同程度的抑制作用.
Two new ternary complexes La(Ala)(3)Im(ClO4)(3) . 3H(2)O(Lal) and La(Ala)(3)BenIm(ClO4)(3) . H2O (La2) of lanthanum perchlorate and DL-alpha-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.
