Antiferromagnets such as the organometallic dithiolene complexes [Cp2M(dmit)] + [X] (M = Mo, W X = PFe, AsFe", SbFe") offer a series of systems that have variable transition temperatures and magnetic anisotropy characteristics. Interestingly, the [Cp W(dmit)2] (28) system is a 15-electron...

Most of the recent work has focused on dithiolenes with organometallic ligands or addressed structural questions relating to their conductive properties (see Section 16.5.4.1). Nevertheless, a few reports on other dithiolenes require mention as well. 

Dithiolenes have been prepared by many unplanned or unusual methods, often involving organometallic intermediates (274). Whereas these transformations are presently classified as specialized, future work may show that these methods enjoy more significance than presently appreciated. The fact that dithiolenes appear in the products of so many reactions is testament to their considerable stability. 

In summary, bis(dithiolene) complexes are clearly distinct from traditional inorganic or organometallic complexes in which the chemical reactivity is dominated by the metal center. The unique properties of dithiolene ligands such as redox activity, aromaticity, and unsaturation of the metal-ligand chelate rings, in combination with the metal-centered reactivity paths, have generated many unusual reactivity patterns for this class of complexes. 

Eisenberg and co-workers (135-137) investigated dithiolene-containing organometallic complexes of Rh and Ir. Addition of an alkyl halide to [Rh(CO)-(PPh3)(mnt) forms a Rh(III) halo acyl complex. The halide can be stripped off by Ag+ salts (135) (Eqs. 30 and 31).
