Despite the [RuF₅NO]²⁻ ion is the simplest of all ruthenium nitrosyls, the information available in the literature is scarce. In this paper the infrared and Raman spectra of NaK[RuF₅NO].H₂O are reported as well as first time Raman spectrum of K₂[RuF₅NO].H₂O. To improve the assignments of RuNO vibrational modes, samples were enriched with ¹⁵N. The electronic spectrum of the [RuF₅NO]²⁻ ion is also studied and the assignments for the vibrational and UV–vis bands were supported by DFT calculations. The thermal stability of K₂[RuF₅NO].H₂O was studied by thermogravimetric (TG) and differential thermal analysis (DTA) of polycrystalline samples under nitrogen and oxygen atmospheres in a temperature range of 20−800 °C.

尽管[RuF ₅ NO] ²⁻离子是所有钌亚硝酰基中最简单的离子，但文献中可用的信息很少。本文报道了NaK [RuF ₅ NO] .H ₂ O的红外光谱和拉曼光谱，以及K ₂ [RuF ₅ NO] .H ₂ O的首次拉曼光谱。为了改善RuNO振动模式的分配，样品中富含^15N。还研究了[RuF ₅ NO] ²⁻离子的电子光谱，并通过DFT计算支持了振动和UV-vis谱带的分配。K ₂ [RuF ₅的热稳定性通过热重法（TG）和差热分析（​​DTA）在20-800°C的氮气和氧气气氛下对多晶样品进行了NO] .H ₂ O的研究。
