Syntheses, Structures and Physical Properties of Palladium Complexes with an Extended-TTF Dithiolate Ligand, Bis(di-n-propylthiotetrathiafulvalenedithiolato)palladate

New palladium complexes with an extended-TTF ligand, (nBu4N)[Pd(C3-tdt)2] and [Pd(C3-tdt)2] were prepared and their crystal structures were determined. The magnetic susceptibility of (nBu4N)[Pd(C3-tdt)2] gave good agreement with the Bonner-Fisher model (J=−16 K), suggesting anions form approximately a one-dimensional antiferromagnetic chain. Neutral [Pd(C3-tdt)2] was a semiconductor with a room temperature conductivity of ca. 10−2 S·cm−1.
