by X-ray diffraction methods. For all these complexes, the central ion is coordinated through the oxygen atom of the carbonyle and the azomethine nitrogen atom of the semicarbazone. The antifungal activity of the complexes and their corresponding ligands was evaluated against some strains of respectively, Candida albicans, Candida glabrata and Aspergillus fumigatus. The complexes with 3STCH and 2,3BSTCH2
氯化镍(II)和溴化物与3-噻吩醛半卡巴zone(3STCH)和2,3-噻吩二甲醛双(半卡巴zone)(2,3BSTCH 2)的反应导致形成一系列新的络合物:[NiCl 2(3STCH)2 ],[NiBr 2(3STCH)2 ],[NiCl(2,3BSTCH 2)(H 2 O)] Cl和[NiBr(2,3BSTCH 2)(H 2 O)] Br。两个配体3STCH,2,3BSTCH 2和配合物[NiBr(2,3BSTCH 2)(H 2O)] Br已通过X射线衍射法测定。对于所有这些络合物,中心离子均通过羰基的氧原子和半卡巴zone的偶氮甲碱氮原子配位。评价了该复合物及其相应配体的抗真菌活性,分别针对白色念珠菌,光滑念珠菌和烟曲霉的某些菌株。与3STCH和2,3BSTCH 2的配合物揭示了有趣的抗C. glabrata的CMI 80值。还对MRC5细胞进行了体外细胞毒性测定。
