abstract = "A new method is proposed to synthesize ethylenediamine complex [RuNO(en)2OH]I2 from K2[RuNOCl5], which increases the target product yield to 76%. Subsequent treatment of nitrate salt [RuNO(en)2 OH](NO3)2 with concentrated HF with the precipitation of HClO4 gives [RuNO(en)2F](ClO4)2 with a quantitative yield. According to the single crystal XRD data, in the [RuNO(en)2F]2+ cationic moiety, nitrosyl and fluoride are in the trans-position relative to each other, and in the ruthenium coordination environment, the equatorial plane is composed of four nitrogen atoms from ethylenediamine ligands. The 450 nm light irradiation of the [RuNO(en)2F](ClO4)2 complex at 80 K results in the formation of metastable linkage isomer MS1 with nitrosyl group coordination through the oxygen atom. According to the IR spectroscopic data, the population of MS1 is about 1%, and the respective vibrational band disappears when heated in a temperature range of 280-310 K. The activation parameters of the MS1–GS (ground state) transition according to the DSC data are Ea = 107.1±6.8 kJ/mol, lnk0 = 36.1±2.6.",
