palladium(II), platinum(II) and silver(I) complexes based on (Δ)- and (Λ)-1,2–bis-(1H-benzimidazol-2-yl)-1,2-ethanediol (Δ-H2bie and Λ-H2bie) enantiomers in the absence and presence of the N,N-chelates 2,2′-bipyridyl and 9,10-phenanthroline, and triphenylphosphine is reported. The molecular structures of the new complexes are discussed on the basis of their IR, Raman, UV–Vis, NMR (1H, 13C and 31P) and
摘要基于(Δ)-和(Λ)-1,2-双-(1H-苯并咪唑-2-基)-1合成了一些新的钯(II),铂(II)和银(I)配合物,据报道,在不存在和存在N,N-螯合物2,2'-联吡啶和9,10-菲咯啉和三苯基膦的情况下,存在2-乙二醇(Δ-H2bie和Λ-H2bie)对映异构体。根据新化合物的IR,拉曼光谱,UV-Vis,NMR(1H,13C和31P)和质谱,元素分析,摩尔电导率和TGA特性对它们的分子结构进行了讨论。Δ-H2bie和Λ-Hbie均通过偶氮甲碱-N和质子化的羟基-O原子以中性双齿配位方式与金属离子结合,而在碱性介质中,Δ-Hbie-和Λ-Hbie-与金属离子结合通过偶氮甲胺-N和去质子化的O原子作为单负性双齿螯合配体。该复合物的体外抗癌活性已针对人乳腺癌(MDA-MB231)和卵巢癌(OVCAR-8)细胞系进行了评估。Δ-H2bie复合物对所研究的细胞系更具活性。[Ag(PPh3)(Λ-H2bie)]
