Models of the iron-only hydrogenase: Structural studies of chelating diphosphine complexes [Fe2(CO)4(µ-pdt)(κ2P,P′-diphosphine)]

Abstract
Six chelating diphosphine complexes, [Fe2(CO)4(µ-pdt)(κ2P,P′-diphosphine)], have been crystallographically characterised allowing differences between basal–apical and dibasal conformations to be analysed.
