Abstract: A new tert-butanol solvate of [{(ⁱPrC₆H₄Me)RuCl}₂{-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-HO hydrogen bond exists between -pyrazine-2,5-dicarboxylato-bis[chlorido(⁶-p-cymene)ruthenium(II)] and the tert-butanol molecule.
