Abstract
Infrared evidence is presented for the formation of a planar three-co-ordinate species, [Fe(CO)(NO)2], on u.v. photolysis of [Fe(CO)2(NO)2] in argon and methane matrices, and for the formation of four-co-ordinate species, [Fe(CO)(N2)(NO)2] and probably [Fe(N2)2(NO)2] In nitrogen matrices at 20 K. The primary photolysis steps are readily reversed by irradiation with visible light. The results are related to the postulate of co-ordinatively unsatur-ated and expanded-co-ordination-shell species as intermediates in the thermal substitution reactions of [Fe(CO)2(NO)2].Keywords
