An apitite for reduction: The diastereoisomers of the tetrachelating ligand 1,3-bis[(5H-dibenzo[a,d]cyclohepten-5-yl)phenylphosphanyl propane, bis(troppPh)propane, can be used to control the redox potentials of 16-electron rhodium(1) complexes. Whereas the R,S-isomer of the ligand enforces a more planar complex which is difficult to reduce, the R,R(S,S)-isomer favors a tetrahedrally distorted structure which is easily reduced to give a stable rhodium(0) complex (see structure, Rh silver, P yellow, C black, H white).
