✦ Synopsis

C Chemical shifts are reported for the ruthenium(II) tris complexes of thirteen 2,Z-bipyridyls and three 1,lO-phenanthrolines and for the osmium(]") bris complexes of five 2,2'-bpyridyls. Chelation induced shifts -&3 are discussed in terms of models for n back-bonding. -C NMR is shown to be a convenient tool for the direct observation of the geometrical isomerism of complexes formed from monosubstituted 13
