Synthesis and Magnetic Properties of a Highly Conducting Neutral Nickel Complex with a Highly Conjugated Tetrathiafulvalenedithiolate Ligand

A neutral nickel complex with the extended tetrathiafulvalene-4,5-dithiolate ligand benzotetrathiafulvalenedithiolate (btdt2-) is synthesized and characterized. From the structural analysis, the
neighboring molecules in this complex are stacked in a different
way compared to the previously reported single-component metal
[Ni(tmdt)2]. The computational studies confirm that the difference
in molecular packing results in the variance of conductivity.
