摘要
合成了新配体联苯乙酮缩氨基硫脲。在２５±０．１℃及Ｉ＝０．１ｍｏｌ·Ｌ￣（－１）ＫＮＯ＿３存在下，在８０％（Ｖ／Ｖ）二甲亚砜混合溶剂中，用ｐＨ法测定了联苯乙酮缩氢基硫脲的酸离解常数以及它与Ｃｕ（Ⅱ），Ｎｉ（Ⅱ），Ｚｎ（Ⅱ），Ｃｏ（Ⅱ）四种金属离子形成二元配合物的稳定性。结果表明，这四种配合物的逐级稳定常数均符合一般规律，与金属离子的Ｉｒｖｉｎｇ－Ｗｉｌｌｉａｍｓ次序一致。
The new ligand 4-acetylbiphenyl thiosemicarba-zone was synthetized, Theprotonation constant of the ligand and stabicity constants of the complexes formed from theligand with copper(Ⅱ),nickel(Ⅱ),cobalt(Ⅱ)and zinc(Ⅱ)have been determined by pHmethod at 25±0.1℃,I=0. 1mol·L￣(-1)(KNO_3)in mixed solvents[80%(V/V)DmSO]. Theresults showed that the successive stability constants of these complexes accord with the gen-eral law and the Irving-Williams order of metal ions.
