[Ni(Pdto)S]2 (CF3SO3)2 , (Pdto = 1,8-bis(2'-pyridyl)-3,6-dithiaoctane), a mixed valence dinuclear complex was synthesized. X-ray crystallographic data showed distinctively longer bond lengths between the Ni(1)-sulfido, and Ni(1)-Pdto , when compared to the respective Ni(2) lengths. Evidence of a mixed valence state was further supported by cyclic voltammetric, spectroscopic, and variable temperature magnetic data. The superexchange pathways will also be discussed in light of Density-Functional theory calculations.
