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 ·2H 2 O (1), crystallized in an acentric space group of P 2 1 2 1 2 1 , with the cell dimensions of a ?=?8.634(1), b ?=?14.560(1), c ?=?49.889(5)?Å, a?=?ß?=???=?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 [Ph 2 Cr][Ni(dddt) 2 ] are also reported.
