摘　　要：研究了体系 Ln^(3+)-SCN^--C_(11)H_(12)ON_2-H_2O(Ln=La、Ce,Pr,Nd,Sm,Dy,Er,Yb,Y,C_(11)H_(12)ON_2=安替比林)中安替比林对 Ln^(3+)的配合行为.首次合成了组成为 Ln(SCN)_3·5C_(11)H_(12)ON_2和 Ln(SCN)_3·4C_(11)H_(12)ON_2的配合物.前者是粘稠胶状物质,后者为晶体,二者在一定条件下可互相转化.对配合物的物理和化学性质进行了初步表征,对其结构和性质作了某些讨论.The coordination behavior of Antipyrine to rare earth ions is investigated in the systems Ln^(3+)-SCN^--Antipyrine-H_2O(Ln=La,Ce,Pr,Nd,Sm,Dy,Er,Yb, Y;Antipyrine,C_(11)H_(12)ON_2).The compounds Ln(SCN)_3·5C_(11)H_(12)ON_2 and Ln(SCN)_3·4C_(11)H_(12)ON_2 have been obtained by the synthesis for the first time. The former compounds are sticky substances,while the later ones are crystals.The physical and chemical properties of these coordination compounds are characterized and their structure is discussed.
