Abstract

The reaction of trans-[Ru(NO)Py ₂Cl ₂(OH)] with concentrated o-phosphoric acid, after washing the mixture with diethyl ether, gave trans-[Ru(NO)Py ₂Cl ₂(H ₂O)]H ₂PO₄ ⋅2H ₃PO₄ ⋅H₂O (I) in nearly quantitative yield. The structure of this compound was determined by X-ray diffraction analysis: space group P-1. Washing of I with ethanol afforded the dihydrophosphate salt trans-[Ru(NO)Py ₂Cl ₂(H ₂O)]H ₂PO₄ ⋅H₂O (II) (yield 97%). The thermal decomposition of I and II in a helium atmosphere resulted in the formation of ruthenium phosphide RuP as a predominant component along with Ru ₂P or RuP ₂. Preliminary photoisomerization experiments for trans-[Ru(NO)Py ₂Cl ₂(OH)] and trans-[Ru(NO)Py ₂Cl ₂(H ₂O)]H ₂PO₄ ⋅H₂O suggested the presence of metastable states. DSC experiments have been carried out for both compounds. The measured kinetic parameters for the metastable decay for trans-[Ru(NO)Py ₂Cl ₂(H ₂O)]H ₂PO₄ ⋅H₂O were E _a = 90.7 ± 2.4 kJ/mol, log ₁₀(k₀/sec ⁻¹) = 18.9 ±0.6, and T _d = 217 K.
