Nine new transition‐metal dithiocarbamates involving ferrocene (Fc), namely, [M(FcCH 2 Bzdtc) 2 ] (M=Ni II ( 1 ), Cu II ( 2 ), Cd II ( 3 ), Hg II ( 4 ), Pd II ( 5 ), Pt II ( 6 ) and Pb II ( 7 ); Bzdtc= N ‐benzyl dithiocarbamate) and [M(FcCH 2 Bzdtc) 3 ] (M=Co II ( 8 ) and UO 2 VI ( 9 )), have been synthesised and characterised by micro analyses, IR spectroscopy, 1 H and 13 C NMR spectroscopy, and in three cases by single‐crystal X‐ray analysis. The peak broadening in the 1 H spectrum of the copper complex indicates the paramagnetic behaviour of this compound. A square‐planar geometry around the nickel and copper complexes and distorted linear geometry around the mercury complex have been found. The latter geometry is attributed to the bulkiness of the methylferrocenyl and benzyl groups. The observed single quasi‐reversible cyclic voltammograms for complexes 2 , 8 and 9 indicate the stabilisation of a metal centre other than Fe in their characteristic oxidation state. These complexes have been used as a photosensitiser in dye‐sensitised solar cells.
