本文合成了配体X(CH_2CH_2CO_2 H)_2(X = O,S,Se,Te),Se(CH_2CO_2 H)_2,X[CH(Me)CO_2 H]_2(X = S或Se)和HO_2CCH_2SCH_2CH_2CO_2 H,并在25 °C和I= 0.10M(K[NO_3])下测定了它们与H ~+,Ag ~+和一些二价金属离子的络合物的形成常数。Ag+的稳定性顺序为Te > Se > SO.
The ligands X(CH2CH2CO2H)2(X = O, S, Se, and Te), Se(CH2CO2H)2, X[CH(Me)CO2H]2(X = S or Se), and HO2CCH2SCH2CH2CO2H have been synthesised and the formation constants of their complexes with H+, Ag+, and a number of bivalent metal ions measured potentiometrically at 25 °C and I= 0.10M(K[NO3]). With Ag+ the stability order is Te > Se > S O.
