New mixed-ligand cobalt(III) dithiocarbomato complexes of the general formula [Co(Et2dtc)2 DTO]-BD4 (where Et2dtc = diethyldithiocarbamato, and DTO is a dithio-oxamide, in particular: unsubstituted dithio-oxamide = H2DTOH2; N,N′-diisopropylDTO = Pr2DTOH2 = N,N′-dicyclohexylDTO = Hex2DTOH2; N,N′-difurfurylDTO = Fur2DTOH2; N,N′-dibenzylDTO = Bz2DTOH2; N,N′-diethylDTO = Et2DTOH2, N,N,N′,N′-tetraethylDTO
通式[Co(Et2dtc)2 DTO] -BD4的新型混合配体钴(III)二硫代氨基甲酸络合物(其中Et2dtc =二乙基二硫代氨基甲酸,DTO为二硫代乙酰胺,特别是:未取代的二硫代乙酰胺= H2DTOH2; N, N'-二异丙基DTO = Pr2DTOH2 = N,N'-二环己基DTO = Hex2DTOH2; N,N'-二糠基DTO = Fur2DTOH2; N,N'-二苄基DTO = Bz2DTOH2; N,N'-二乙基DTO = Et2DTOH2,N,N,N',已经制备了N'-四乙基DTO = Et4DTO,通过元素分析和电导率测量进行表征,并通过振动和电子光谱法进行了研究。基于这些基础,建议二硫代草酰胺充当二齿硫配体。
