A new paramagnetic Pd(dmit)(2) salt: Tris(2,2 '-bipyridine)nickel(II) bis(1,3-dithiole-2-thione-4,5-dithiolato)palladate(II) mono-acetonitrile; [Ni(bpy)(3)][Pd(dmit)(2)] center dot CH3CN

摘要

Combination of the [Ni(bpy)(3)](2+) cation complex and the [Pd(dmit)(2)](-) anion (dmit=C3S52- = 1,3-dithiole-2thione-4,5- dithiolate) has resulted in the paramagnetic [Ni(bpy)(3)][Pd (dmit(2)] . CH3CN compound, a suitable precursor for a molecular magnetic conductor. Its crystal structure consists of a Pd(dMit)(2) anion arrangement that is quite different from segregated stack layers often found for M(dmit)(2)-based compounds. The reduction of the [Pd(dMit)(2)](-) to the 2- charged anion in the title compound most probably is the result of a charge disproportionation between Pd(dMit)(2) anions.
