Abstract Five coordination complexes with Mn2+ (1), Co2+ (2), Ni2+ (3), Cu2+ (4), and Zn2+ (5) containing acesulfame (ace) and N,N-diethylnicotinamide (dena) ligands were synthesized and structural binding properties investigated. Four compounds (1, 2, 4, and 5) were examined with single crystal X-ray diffraction methods. The structures containing Mn(II), Co(II), and Zn(II) were iso-structural. Six-coordination of metal cations were completed with two moles dena and four aqua ligands. The dena ligands were coordinated via pyridine nitrogen as neutral-monodentate. Charge stabilities of the complexes are complemented by two moles monoanionic ace ligands, located outside of the coordination unit. In the Cu(II) complex, the coordination is completed by acidic nitrogen and carbonyl oxygen atoms of two ace ligands and pyridine nitrogen of two moles dena ligands. The coordination to Cu(II) for ace ligands was monoanionic-bidentate. All metal cations in the structure are distorted octahedral. Thermal decomposition of complexes begins with removal of the aqua molecules from the structures and is completed by combustion of organic ligands. The final decomposition products of all structures have been identified as corresponding metal oxides. Some biological applications (anti-fungal/anti-bacterial) were studied using 1–5.

新型配位化合物:Mn(II)、Co(II)、Ni(II)、Cu(II) 和 Zn(II) 阳离子与乙酰磺胺酸/N,N-二乙基烟酰胺配体

摘要 合成了含有安赛蜜 (ace) 和 N,N-二乙基烟酰胺 (dena) 配体的 Mn2+ (1)、Co2+ (2)、Ni2+ (3)、Cu2+ (4) 和 Zn2+ (5) 五种配位配合物并进行了结构结合。属性进行了调查。四种化合物(1、2、4 和 5)使用单晶 X 射线衍射方法进行检测。含有 Mn(II)、Co(II) 和 Zn(II) 的结构是同构的。金属阳离子的六配位由两摩尔的 dena 和四个水配体完成。dena 配体通过吡啶氮配位为中性单齿。复合物的电荷稳定性由位于配位单元外部的两摩尔单阴离子 ace 配体补充。在 Cu(II) 络合物中,配位是由两个ace配体的酸性氮和羰基氧原子以及两摩尔dena配体的吡啶氮完成的。ace 配体与 Cu(II) 的配位是单阴离子双齿的。结构中的所有金属阳离子都是扭曲的八面体。复合物的热分解开始于从结构中去除水分子,并通过有机配体的燃烧完成。所有结构的最终分解产物已被确定为相应的金属氧化物。使用 1-5 研究了一些生物学应用(抗真菌/抗菌)。图形概要 复合物的热分解开始于从结构中去除水分子,并通过有机配体的燃烧完成。所有结构的最终分解产物已被确定为相应的金属氧化物。使用 1-5 研究了一些生物学应用(抗真菌/抗菌)。图形概要 复合物的热分解开始于从结构中去除水分子,并通过有机配体的燃烧完成。所有结构的最终分解产物已被确定为相应的金属氧化物。使用 1-5 研究了一些生物学应用(抗真菌/抗菌)。图形概要
