We report the synthesis of a new completely planar, extensively conjugated bimetallic Ni(II) complex for the construction of new molecular metals. The complex, (Bu(4)N)(2) {tto[Ni9dmit)](2)} (1), with 14 sulfur atoms in the periphery, has Ni(II) metal centers bridged by the tetrthiooxalate (tto) ligand and capped with dmit (dmit=C3S52-=2-thioxo-1,3-dithiole-4,5-dithiolato) ligands. This is the first completely planar complex with tto bridging Ni(II) metal centers. Reation of 1 with (TTF)(3)-(BF4)(2) forms a conducting material with a high pressed-pellet conductivity of 0.4 s/cm.
