A series of complexes [M(CO)5(Hdpf-κP)], where M = Cr (1), Mo (2) and W (3), and Hdpf is 1'-(diphenylphosphanyl)ferrocenecarboxylic acid, was obtained by thermally-induced (2) or photochemically-assisted (1, 3) displacement of carbon monoxide with Hdpf from the corresponding hexacarbonyl complexes. The complexes were characterized by NMR, UV-VIS and IR spectroscopies and further studied by cyclic voltammetry. The solid-state structure of complex 1 has been determined by single-crystal X-ray diffraction.
