The first arenediazo derivatives of iron(-II), Fe(N2Ar)(NO)(CO)(PPh3), have been synthesised and their properties are described.A linear relationship has been found between ν(CO) in these complexes and ?- for the para substituent in the arenediazo aryl ring.The 57Fe MOessbauer spectra of the complexes indicate that + is a stronger ?-donor and weaker ?-acceptor than +.The relationship between ΔEq and ?-p suggests that changes in ΔEq with aryl substitution involve both substituent-specific and substituent-independent effects.The unstable cobalt(-I) compound Co(N2C6H5)(CO)2(PPh3), the first arenediazo derivative of cobalt, is also described.
