Charge‐Transfer Complexes Dinuclear nickel complexes supported by macrocyclic hexaaza‐dithiophenolate ligands form a unique class of stable thiolate→halogen CT complexes (Hal = Br or I), in which short S−Hal bonds are always correlated to long Hal−Hal bonds and vice versa. The donating ability of the bridging thiolate functions was found to be similar to those of thioether or thiones as suggested...
The dinuclear nickel complexes [Ni2L(μ‐O2CR)](ClO4) [R=Me (4), R=OMe (6)], where L2− is a 24‐membered macrocyclic N6S2 ligand, react readily with excess I2 in MeCN solution at 4 °C to form stable mono‐(I2) and bis‐(I2) charge‐transfer (CT) adducts of the type [Ni2L(μ‐O2CR)(I2)n]+ (n=1 or 2) containing linear RS‐I‐I linkages. Three new CT compounds, namely, [Ni2L(OAc)(I2)](I2)(I3) (5), [Ni2L(O2COMe)(I...
