The molecular structure of O(C6H4)2AsS2CN(CH2CH2)2 was determined using single-crystal X-ray diffraction. The compound is monomeric and contains an asymmetric monometallic biconnective dithiocarbamato unit (AsS(1), 2.277(1), Å; As⋯S(2), 3.183(3) Å). The double-bond character of the CN bond (1.318(5) Å) is in agreement with the NMR data. The dihedral angle (155.2°) of the phenoxarsine moiety is almost
苯恶草素-10-基二硫代氨基甲酸酯O(C 6 H 4)2 AsS 2 CX(X = NMe 2,NEt 2,N(CH 2 CH)2,N(CH 2 CH 2)2或CH(CH 3)CH 2 ])是通过O(C 6 H 4)2 AsCl与二硫代氨基甲酸钠反应制得的。通过IR,质谱和NMR(1 H和13 C)光谱对化合物进行表征。O(C 6 H 4)2的分子结构使用单晶X射线衍射测定AsS 2 CN(CH 2 CH 2)2。该化合物是单体的,并包含一个不对称的单金属双连接的二硫代氨基甲酸酯单元(As1S(1),2.277(1),Å; As⋯S(2),3.183(3)Å)。CN键(1.318(5)Å)的双键特征与NMR数据一致。苯恶ar碱部分的二面角(155.2°)几乎不受二硫代氨基甲酸酯配体取代氯的影响。
