Mixed-valence triiron complexes Fe(3)(CO)(7-x)(PPh(3))(x)(mu-edt)(2) (x = 0-2) have been prepared and are shown to act as proton reductioncatalysts. Catalysis takes place via an ECEC mechanism with a reduced overpotential of ca. 0.45 V for Fe(3)(CO)(7)(mu-edt)(2) as compared to the corresponding diiron complex.
