N2 - An ionic metal-dithiolene complex, 1,1'-didecyl-4,4'-bipyridinium bis(maleonitriledithiolato)zincate(II) ([Zn(mnt)2]2-), was synthesized and characterized by elemental analysis, infrared spectroscopy and crystal structure. In the [Zn(mnt)2]2- moiety, the complex shows distorted tetrahedral geometry with Zn2+ coordinated to four S-atoms from two mnt2- ligands, and its long molecular axis adopts a similar orientation with 1,1'-didecyl-4,4'-bipyridinium. Two distinguishable redox processes occur in the voltage region of - 1.0 to 1.0 V, with the irreversible and reversible redox couples corresponding to [Zn(mnt) 2]2-/[Zn(mnt)2]- and 1,1'-didecyl-4,4'-bipyridinium+/1,1'-didecyl-4,4'-bipyridinium 2+, respectively. An uncommon nematic mesophase behavior in this complex was confirmed by polarized-light optical microscopy (POM) and differential scanning calorimetry (DSC) measurements.
