Abstract The syntheses of two new monothiocarbamate ligands and selected transition element complexes of each are reported. The complexes of indoline-N-carbothioate (intc) prepared are: NiL2·1.5H2O, ZnL2, NiL2·2py, ZnL2·2py. The complexes of indole N-carbothioate (iltc) are: NiL′2, ZnL′2, Cul′. IR spectral results support a bidentate ligand behavior for both new monothiocarbamates except in ZnL2·2py
摘要报道了两个新的单硫代氨基甲酸酯配体的合成及其各自的过渡元素配合物。制备的吲哚啉-N-硫代碳酸盐(intc)的配合物为:NiL2·1.5H2O,ZnL2,NiL2·2py,ZnL2·2py。吲哚N-硫代碳酸盐(iltc)的配合物为:NiL'2,ZnL'2,Cul'。红外光谱结果支持两种新的单硫代氨基甲酸酯的双齿配体行为,但在ZnL2·2py中除外。比较二(吲哚基氨基甲酰基)-二硫化物的红外光谱特征与配位的吲哚-N-氨基甲硫醇酸酯的红外光谱特征,可以确定CS和CO的振动频率。提出了对每个新配体的电子结构的主要共振贡献不同的证据。还介绍了双(吲哚基氨基甲酰基)二硫化物的晶体结构,并与吡咯-N-碳硫代硫酸盐进行了比较,另一种芳香胺一硫代氨基甲酸酯。二硫化物在中心对称单斜空间群P21 / c中结晶,a = 15.64(4)A,b = 5.228(1)A,c = 19.271(7)A,β= 97.20(2)°,V
