First Iridium(IV) Chloride-Dimethyl Sulfoxide Complex [H(dmso)2][IrCl5(dmso-κO)]: Synthesis and Structure along with Novel Polymorph Modifications of [H(dmso)2][trans-IrCl4(dmso-κS)2] and [H(dmso)][trans-IrCl4(dmso-κS)2].

ABSTRACT: As evidenced by UV-Vis and EPR spectroscopies, the reaction of H2IrCl6·6H2O or Na2[IrCl6]·nH2O with DMSO results in a slow reduction of Ir(IV) avoiding the formation of Ir(IV) dimethyl sulfoxide complexes in measurable quantities. More specifically, we successfully isolated and solved the crystal structure of a sodium hexachloridoiridate(III), Na3[IrCl6]·2H2O, as a product of Na2[IrCl6]·nH2O reduction in an acetone solution. Furthermore, it was shown that [IrCl5(Me2CO)]- species is gradually formed in an acetone solution of H2IrCl6·6H2O upon storage. The reaction of DMSO with aged
