Rhodium or iridium complexes of formula + have been prepared by treating 2 complexes with silver salts and azulene, and also by treating + with azulene.The reactions of some representative complexes have been studied.Reaction of 2+ with azulene appears to give dinuclear diazulene cationic complexes.The crystal structure of compound PF6 has been solved by X-ray methods.It crystallizes in the space group P21/c with cell constants 8.4241(4), 16.6911(8), 15.0026(7) Angstroem, 95.897(6) deg.Refinement gave R=0.027 and Rw=0.032 for 2991 observed reflexions.The Rh atom is coordinated to the five-membered ring, with Rh-C distances shortest for the atoms which are trans to the diolefinic double bonds.The bonding scheme within the azulene ligand differs from that in the parent hydrocarbon.
