Rhodium and iridium complexes of the title ligands have been prepared containing cyclooctadiene, carbonyl, phosphine and phosphite ancillary ligands. The complexes are mononuclear or dinuclear depending on the method of preparation and the leaving group basicity. The geometries of the complexes derived from the 2,3- and 2,5-dianions show marked differences owing to differences in the steric interaction between the carboxyl groups. Clear structural assignments were made possible by the symmetry requirements revealed by the infrared and NMR spectra. © 1990.
