چکیده
A new tert-butanol solvate of [{((i)PrC(6)H(4)Me)RuCl}(2){μ-2,5-pyz(COO)(2)}] (pyz = pyrazine) has been crystallized and structurally characterized. The solvate, [Ru(2)(C(10)H(14))(2)(C(6)H(2)N(2)O(4))Cl(2)]·2C(4)H(10)O, contains one half-mol-ecule of the ruthenium(II) complex and one mol-ecule of tert-butanol in the asymmetric unit. The complex mol-ecule 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 inter-molecular O-H⋯O hydrogen bond exists between μ-pyrazine-2,5-dicarboxyl-ato-bis-[chlorido(η(6)-p-cymene)-ruthenium(II)] and the tert-butanol mol-ecule.
