Abstract Hereby we present the synthesis of several ruthenium (II) and ruthenium (III) dithiocarbamato complexes. Proceeding from the Na [trans-Ru III (dmso) 2 Cl 4](2) and cis- [Ru II (dmso) 4 Cl 2](3) precursors, the diamagnetic, mixed-ligand [Ru II L 2 (dmso) 2] complexes 4 and 5, the paramagnetic, neutral [Ru III L 3] monomers 6 and 7, the antiferromagnetically coupled ionic α-[Ru III 2 L 5] Cl complexes 8 and 9 as well as the β-[ ...
