Rhodium(I) and iridium(I) complexes of the formulae M(PyBzIm)(diolefin), ClO4, (diolefin)M(μ-PyBzIm)AuCl, <(diolefin)M(μ-PyBzIm)AuL>ClO4 (L = PPh3 or P(OMe)3), <(diolefin)M(μ-PyBzIm)AgPPh3>ClO4 and 2>ClO4 (diolefin = COD or NBD) are described.The related carbonyl derivatives M(PyBzIm)(CO)Y, ClO4 (Y = CO or PPh3), (CO)2M(μ-PyBzIm)AuCl, <(CO)2Rh(μ-PyBzIm)AuP(OMe)3>ClO4, 2>ClO4 and 2>ClO4 have been obtained by reaction of diolefin derivatives with carbon monoxide and triphenylphosphine.
