Dithiocarbamate [ s2cnr2 ( dtc ) ] and it ' s derivates were applied in chemistry 、 medical 、 petrochemical and other fields, it can coordinated with all kinds of transition metals, the anion of bidentate ligand also bridges two transition metals
摘要氨荒酸鹽[ s2cnr2 ( dtc ) ]及其衍生物早已廣泛應用於化學、醫學、石油化工等領域,它與所有的過渡金屬都可以進行配位,形成螯合物,雙齒的陰離子也可以作為橋鏈兩個過渡金屬的配體。Both the frequency and intensity of 1146. 0cm - 1 change largely, etc. discussed and compared the mechanism of these interaction in detail we got some conclusions as following : both zn2 + and cd2 + ions can chelate with po2 - and come into being - po2 - me2 + n7 ( purine ) chelate. as to zn2 + ions, when r2. 0, the quantity of po2 - zn2 + n7 is directly linear with r. when r2. 0, zn2 + ions even can chelate with c at n3 - o2 sites and this chelation will disrupt the h - bond between gc base pairs and make the dna structure unstable. as to cd2 + ions, only when r is within 1. 0 - 1. 5 can this chelation take place and the relation of the quantity of this chelate with r is not easy to conclude
通過對這些變化進行詳細討論和分析,我們得到了如下的結論: zn ~ ( 2 + )和cd ~ ( 2 + )都可以跟dna的磷酸基團螯合,形成- po _ 2 ~ - … me ~ ( 2 + ) … n7 ( g )螯合物,但是前者的螯合跟離子濃度有很大的關系,在摩爾濃度比小於2 . 0時,螯合物的生成量跟r成正比關系,而後者的螯合跟離子的關系不是很明顯,只有當r處於1 . 0至1 . 5之間時,螯合作用才能進行,並且螯合物的生成量跟r之間沒有很明顯的關系存在。
