“…It is apparent that the major differences the dmio ligand makes are the use of the dmio oxygen atom in coordination to the non-chelated Hg atom, and its involvement in pÁ Á Áp and HgÁ Á Áp interactions. Despite these, the Hg-S bond lengths in both 4 and [(PhHg) 2 The insolubilities of 1 and 3 in common organic solvents and the affinity of Hg for sulfur suggest that these compounds would possess strong intermolecular Hg-S interactions, especially, but not necessarily, to the thione sulfur atoms, and hence will be polymeric species. Such metal-sulfur interactions have been reported in organotin, [ would arise from the lack of any pÁ Á Áp interactions involving the phenyl group, but this is not considered to lead to any major structural change.…”

“…The compounds precipitated on mixing the reagents and were found to be very poorly soluble in common organic solvents. The only compound which provided suitable crystals for a single crystal X-ray study was [(PhHg) 2 [57], dmio [26,58,59] and dmt [27,28,60,61] species.…”

“…1, has attracted much attention [1], since the first efficient syntheses were reported in the 1970s [2]. The great interest in metal complexes of these ligands, especially of d 8 transition metals of [dmit] 2À has stemmed largely from such applications as superconducting materials [3][4][5][6][7][8].…”

“…Z[Ni(dmit) 2 ] x (Z is mono-cation) type complexes, because of their structural diversity and electrical conductivity, have received great attention [1] since the multi-sulfur ligand dmit ðC 3 S 2À 5 Þ was first reported in the mid 1970's [2]. Historically, dmit was the abbreviation of 4,5-dimercapto-1,3-dithiole-2-thione, which has now been renamed to 2-thioxo-1,3-dithiole-4,5-dithiolato.…”

Enantiomerically pure dithiolene complexes NBu4[Ni[(R,R)-diotte)2] and NBu4[Ni((S,S)-diotte]2] (diotte2- = a 1,3-dioxolane-tetrathiaethylene), were prepared from the corresponding enantiomers of a diotte2- precursor. The structure of the precursor was solved by single-crystal X-ray analysis; desulfurization afforded a novel tetrathiafulvalene derivative. Combination of the complex monoanion with the enantiomers of the viologen derivative bis(2-methyl-3-hydroxypropyl)-4,4'-dipyridinium (HiBV2+) afforded enantiomeric and diastereomeric ion-pair complexes of the type HiBV[Ni(diotte)2]2. For comparison, the analogous compounds A[Ni(diotte)2]2, (A2+ = methyl (MV2+), octyl (OV2-), stearyl (StV2+) viologen or two 2,2'-bipyridinium acceptors), HiBV-[Ni(diotte)L] [L = mnt2- (maleonitrile-1,2-dithiolate), dmit2- (2-thioxo-1,3-dithiol-4,5-dithiolate)], MV[Ni(dmit)2)]2, [Ni(diotte)2], and [Ni(diotte)(dmit)] were synthesized. An X-ray powder diffraction structural analysis of MV-[Ni(dmit)2)]2 revealed the presence of mixed stacks that contain the sequence anion-anion-cation. While no short contacts are observable within a stack, these are observed between the stacks for the dication-anion interaction by short S...H distances in the range of 2.77 to 2.86 A, and for the anion-anion interaction short S...S distances of 3.55 to 3.65 A. In agreement with the absence of intrastack interactions, no ion-pair charge-transfer band can be detected in this and the other complexes. ESR and UV/Vis data suggest that in [Ni(diotte)2]- electron delocalization is less pronounced than in the corresponding mnt2- and dmit2- complexes. The specific electrical conductivity (sigma) of pressed powder pellets ranges from 10(-2) to 10(-12) ohm(-1) cm(-1) and in all cases increases with increasing temperature (293 - 393 K) according to an Arrhenius law. Corresponding activation energies vary from 0.14 to 0.93 eV and increase linearly with log a for structurally similar ion pairs. Charge generation is postulated to occur by disproportionation of the monoanion as suggested by the almost linear increase of log(sigma) with decreasing disproportionation energy. The conductivity of diastereomers of ions with two unlike configurations like [(S,S)-HiBV]-[Ni[(R,R)-diotte]2]2 (1.1 x 10(-1) ohm(-1) cm(-1)) is one to two orders of magnitude higher as compared to the diastereomers with two like-configured ions.
