Preparation of cis-diamminediaquaplatinum(II) nitrate

摘要

A process is provided for preparing cis- Pt(NH.sub.2).sub.3 (H. sub.2 O) .sub.2 !(NO.sub.3).sub.2 by a process comprising preparing cis- Pt(NH.sub. 3).sub.2 I.sub.2 from K.sub.2 PtI.sub.4 under controlled conditions of temperature and pH and converting the resultant cis-Pt(NH. sub.3).sub.2 I. sub.2 to the diaqua complex with AgNO.sub.3 under controlled conditions.
