A series of pentaamminerhodium(III) complexes, Rh(NH/sub 3/)/sub 5/Z/sup n+/, has been prepared with 80% enrichment in /sup 15/N (Z = H/sub 2/O, OH/sup /minus//, Cl/sup /minus//, Br/sup /minus//, I/sup /minus//, NH/sub 3/, /minus/ONO/sup /minus//, /minus/NO/sub 2//sup /minus//, /minus/NCS/sup /minus//, /minus/SCN/sup /minus//, /minus/NCO/sup /minus//, CN/sup /minus//). The /sup 1/H-decoupled /sup 15/N NMR spectra show two doublets (from coupling to /sup 103/Rh) with approximate intensity ratio 4:1. /delta//sub N/ and /sup 1/J(rh-N) are sensitive to Z, especially for the unique amine trans to Z. Good correlations exist between /delta//sub N/ in this series of /delta//sub N/ in this series and /delta//sub N/ in the corresponding cobalt(III) complexes Co(NH/sub 3/)/sub 5/Z/sup n+/ and platinum(II) complexes Pt(NH/sub 3/)/sub 3/Z/sup m+/, J(Rh-N) trans to Z also correlates well with H(Pt-N) trans to Z in the platinum series. 16 refs., 2 figs., 1 tab.
