Abstract: The crystal structure analyses along with other physical measurements of 1,2-dithiolene complexes have made it possible to derive many interesting properties of these complexes. This review focuses attention mainly on the structural aspects and physical properties of 1,2-dithiolene complexes of transition metals. Brief mention of the structural aspects of complexes such as 1,2-dithiooxalate complexes and dithiosquarate complexes is included. In addition, structural aspects of a few available non-transition metal complexes are briefly discussed. The idea that bulky counterions lead to nonplanar structures has been disproved by the nonplanarity observed in the anion of [(CH3)4N]2[Cu(S2C2(CN)2)2]. The analysis of the significance of overall charge shows that the ionic effect is prevalent in [M(dithiolene)2]n- systems. Crystal structure analyses of some bis(dithiolene) complexes of transition metals along with conductivity measurements have shown that it is possible to correlate the electrical behavior to the crystal structure, provided the sample crystals are good. The two-dimensional network structure of the mixed valence compound, [(n-C4H9)4N]0.29 [Ni(S2C2S2CS)2], proposes the possibility of reaching the ultimate goal (superconductivity) with this type of compounds. ? 1986 Plenum Publishing Corporation.
