Abstract
In(C6F5)3·D(D=CH3CN, O(C2H5)2)와 (CH3)3SiC6F5/CsF, C6F5MgBr 또는 Cd(C6F5)2을 반응시켜 [In(C6F5)4]- 음이온 화합물을 합성하였으나, 이들 indium(III) 음이온 화합물들은 온도에 민감하고 습기에 대해 불안정하다. 안정한 indium(III) 음이온 착물은 PNPCl(PNP=bis(triphenylphosphino)ammonium)과의 양이온 치환반응시켜 얻었으며, 관 크로마토 그래피를 이용하여 분리 정제하였다. 합성된 화합물의 특성은 핵자기 공명 분석법, 적외선 분광분석법, 분자량 측정, DTA/TG 그리고 원소분석법을 이용하여 조사하였다.

The anionic complexes, [ln(C6F5)4]-, which are thermal and moisture sensitive, have been prepared by the reaction of In(C6F5)3·D(D=CH3CN, O(C2H5)2) with the system (CH3)3SiC6F5/CsF, C6F5MgBr or Cd(C6F5)2. The stable anionic indium(III) complexes are obtained through cation exchange with PNPCI ([PNP]= bis(triphenylphosphino)ammonium). The pure substance is obtained by column chromatography. These new anionic complexes are unambiguously identifed by NMR-spectroscopy, IR spectroscopy, molecular weight, DTA/TG and elemental analysis.
