| 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. |
