spectra and it was confirmed by single-crystal X-ray analysis of potassium-Δ-(−)589-s-cis-oxalato-(S,S)-ethylenediamine-N,N′-di-(2-propanoato)-cobaltate(III)-semihydrate, K-Δ-(−)589-s-cis-[Co(S,S-eddp)(ox)]·0.5H2O. Antimicrobial activity of ligands and obtained cobalt(III) complexes was evaluated by determining the minimum inhibitory concentration (MIC) and minimum microbicidal concentration (MMC) in relation
摘要八面体钴(III)与(S,S)-乙二胺-N,N'-二-2-丙酸(S,S-eddp)和(S,S)-乙二胺-N,N'-di-制备并表征了2-(3-甲基)-丁酸(S,S-eddv)酸和草酸酯和丙二酸酯配体,作为另外的二齿配体。通过离子交换色谱法纯化复合物。根据红外光谱,电子吸收光谱和NMR光谱推测了配合物的几何形状。分离的复合物的Δ绝对构型已经根据其圆二色性(CD)光谱进行了预测,并且通过钾-Δ-(-)589-s-顺式草酸钾的单晶X射线分析得到了证实。 (S,S)-乙二胺-N,N'-二-(2-丙酰基)-钴(III)-半水合物,K-Δ-(-)589-s-顺式-[Co(S,S-eddp) (ox)]·0.5H2O。通过确定相对于13种微生物(5种致病细菌,5种致病真菌和3种微生物)的最小抑菌浓度(MIC)和最小杀微生物浓度(MMC)来评估配体和所得钴(III)配合物的抗菌活性益生菌)。经测试的配
