Description
In treatment of trans-[Ru(NO)(NH3)4(OH)]Cl2 with concentrated sulfuric acid on heating trans-[Ru(NO)(NH3)4(SO4)](HSO4).H2O (I) is obtained with a yield close to quantitative. In the interaction of the saturated solution of I with a saturated NaNO3 solution a trans-[Ru(NO)(NH3)4(SO4)]NO3.H2O (II) precipitate forms whose structure is determined by single crystal XRD: space group P212121, a = 6.8406(3) Aa, b = 12.6581(5) Aa, c = 13.3291(5) Aa. A monodentately coordinated sulfate ion is in the trans-position to the nitroso group. Compound II is characterized by IR spectroscopy, powder XRD, and diffuse reflectance spectroscopy. The process of its thermolysis is studied; by differential scanning calorimetry the thermal effect of the dehydration reaction occurring on heating to 120 C (ΔH = 58.9 ± 1.5 kJ/mol) is estimated. The final product of the thermolysis of II is a mixture of Ru and RuO2.
