Abstract
A series of new complexes of multi-sulfur 1,2-dithiolene ligands, [Ru(bipy)3][Ni(L)2]2 (bipy = 2,2′-bipyridine; L = pddt (6,7-dihydro-5H-1,4-dithiepin-2,3-dithiolate), dddt (5,6-dihydro-1,4-dithiin-2,3-dithiolate)), have been synthesized and characterized. One typical complex, [Ru(bipy)3][Ni(pddt)2]2·2H2O (1), crystallized in an acentric space group of P212121, with the cell dimensions of a = 8.634(1), b = 14.560(1), c = 49.889(5) Å, α = β = γ = 90°, and Z = 4. It consists of alternating columns of cations and anions along the a direction. The structure was refined by full matrix least squares methods to R 1 = 0.0340, wR 2 = 0.0670. Magnetic studies on [Ph2Cr][Ni(dddt)2] are also reported.
