Abstract
A new tert-butanol solvate of [{(iPrC6H4Me)RuCl}2{μ-2,5-pyz(COO)2}] (pyz = pyrazine) has been crystallized and structurally characterized. The solvate, [Ru2(C10H14)2(C6H2N2O4)Cl2]·2C4H10O, contains one half-molecule of the ruthenium(II) complex and one molecule of tert-butanol in the asymmetric unit. The complex molecule lies on an inversion centre with the two chlorides trans. In contrast, the previously reported structure was solvent-free. Similar metric parameters are found between the butanol solvate and the solvent-free form and an intermolecular O—H⋯O hydrogen bond exists between μ-pyrazine-2,5-dicarboxylato-bis[chlorido(η6-p-cymene)ruthenium(II)] and the tert-butanol molecule.
