在含三乙胺的乙腈溶液中，用锌的电化学氧化和2-（二甲氨基）乙硫基二硫化物的同时还原制备了[Zn{SCH 2CH 2N（CH 3）2}2]。晶体属正交晶系，空间群P212121，晶胞参数a = 22.010（5），B= 11.313（3），c = 10.170（3）nm。该结构由两个晶体学上独立的中性单体单元组成，它们是光学异构体。每个锌原子与两个氮原子和两个硫原子键合，产生扭曲的四面体配位几何结构。红外光谱、核磁共振氢谱和碳谱也证实了配体的螯合作用。
The preparation of [Zn{SCH2CH2N(CH3)2}2] by electrochemical oxidation of zinc and simultaneous reduction of 2-(dimethylamino)ethanethiol disulphide in an acetonitrile solution containing triethylamine is described. The compound crystallizes in the orthorhombic space groupP212121witha= 22.010(5),b= 11.313(3) andc= 10.170(3) Å. The structure consists of two crystallographically independent neutral monomeric units, which are optical isomers. Each zinc atom is bonded to two nitrogen and two sulphur atoms yielding a distorted tetrahedral coordination geometry. The chelating behaviour of the ligand is also evidenced in the IR and1H and13C NMR spectra.
