Synthesis, Structural Characterization, Solution Chemistry, and Preliminary Biological Studies of the Ruthenium(III) Complexes [TzH][<i>trans</i>-RuCl<sub>4</sub>(Tz)<sub>2</sub>] and [TzH][<i>trans</i>-RuCl<sub>4</sub>(DMSO)(Tz)]·(DMSO), the Thiazole Analogues of Antitumor ICR and NAMI-A
Two ruthenium(III) complexes bearing the thiazole ligand, namely, thiazolium (bisthiazole) tetrachlororuthenate (I, TzICR) and thiazolium (thiazole, DMSO) tetrachlororuthenate (II, TzNAMI) were prepared and characterized. The crystalstructures of both complexes were solved by X-ray diffraction methods and found to match closely those of the corresponding imidazole complexes. The behavior in aqueous
