The reaction of the dibenzotetraazafulvalene C6H4(NC2H5)2C=C(NC2H5)2C6H4, 1 = 1, with [(COD)Rh(μ-Cl)2Rh(COD)] proceeds via cleavage of the C=C double bond and yields the carbene complex [(COD)RhCl(1)], 2. The X-ray structure analysis shows 2 to be a mononuclear complex with a rhodium(I) center coordinated in a slightly distorted square-planar fashion.
