New high‐yielding methods for two [RuNO(NH 3 ) 3 Cl 2 ]Cl complexes are suggested. First, the ammine ligands are arranged facially through the reaction of a concentrated ammonia solution with the ruthenium–hexanitro complex. In the next step, the treatment of the previously unknown fac ‐Na[Ru(NO 2 ) 3 (NH 3 ) 3 ] · 3H 2 O with hydrochloric acid leads to the nitrosyl complex. The mer ‐[RuNO(NH 3 ) 3 Cl 2 ]Cl · H 2 O complex is formed from the corresponding aqua complex under reflux in 6 m HCl. The complexes were studied by various methods [FTIR spectroscopy, 14 N NMR spectroscopy, extended X‐ray absorption fine structure (EXAFS), thermogravimetric analysis (TGA), and X‐ray diffraction studies]. Metastable states (Ru–O–N) were observed in mer ‐[RuNO(NH 3 ) 3 Cl(H 2 O)]Cl 2 , mer ‐[RuNO(NH 3 ) 3 Cl 2 ]Cl · H 2 O, and fac ‐[RuNO(NH 3 ) 3 Cl 2 ]Cl under illumination at λ = 443 nm at liquid‐nitrogen temperatures.
