Main group derivatives of a cyclometallated iron carbonyl anion. Crystal structures of Fe(CO)2{P(OPh)3}{(PhO)2POC6H4}(SnPh3) and two isomers of Fe(CO)2{P(OPh)3}{(PhO)2POC6H4}(I)
“…To this end we have plotted the averages of the two infrared absorption bands for all complexes documented in the literature against the known iron oxidation state. [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36] z The left hand side of the plot shown in Fig. 3 shows the evident correlation between the observed oxidation states and the averages of the IR absorption bands.…”
Infrared data for mono-iron complexes possessing two cis-CO together with Mössbauer data for the enzyme and a model complex support the assignment that the iron centre of the cluster-free hydrogenase Hmd is low-spin Fe(II).

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
