Tetra-n-butylarnmonium bis(2,3-diferrocenyl-1,4-dithiin-5,6-dithiolato) nickel(Ⅲ) complex, TBA[N_1(dfcvdt)_2], is prepared and crystallizes (orthorhombic, Pnma, a=20.457, b=39.220, c=8.496A, V=6817Aand Z=4), in which ferrocenes are covalently connected to dithiolene ligand. It shows strong near-IR absorption (λ_max=1155nm, log=4.06dm^3/mol cm). Upon treatment of I, TBA complex is oxidized to neutral one, [Ni(dfcvdt)_2]^0, as Ni(dddt)_2 complexes are. Pressed pellet conductivity of neutral complex is measured as 10^-3 S/cm at room temp.
