Ruthenium complexes containing molecular nitrogen

Carbonyl ammine complexes of ruthenium(II)

“…The complex products obtained are always diamagnetic, indicating no oxidation. This behavior is similar to that observed with nitrosylruthenium complexes (4) but not with the corresponding nitrogen complexes (8) where oxidation to ruthenium(II1) occurs more readily. The carbonyl group can, however, be replaced by nitric oxide by treatment with aqueous nitric acid.…”

“…Table 11. By comparison with similar ruthenium complexes (8,9), all bands can be assigned to coordinated ammonia vibrations, except for the following. In the carbonyl complexes a strong band in the region 1970-1 890 cm-l, is assigned to v,-, (Table 111), and another two bands in the region 500-600 cm-', 6,-, and vM-, (12)(13)(14).…”

“…In the carbonyl complexes a strong band in the region 1970-1 890 cm-l, is assigned to v,-, (Table 111), and another two bands in the region 500-600 cm-', 6,-, and vM-, (12)(13)(14). In the nitrogen complexes a strong band in the region 2120-2080 cm-' is assigned to vN, and another in the region 450-550~m-~ to vM, (8). A high energy shoulder on the p , , , band in the region 850-780 cm-' for all aquotetrammine complexes is assigned to coordinated water (15).…”

“…These are generally of the type (4) and -tetrammines (9, sulfur dioxide-tetrammines (6) and -pentammines (7), and nitrogenpentammines (8) are known. We now report the preparation and characterization of some carbonyl-ammine-ruthenium(I1) complexes and nitrogenaquotetrammine-ruthenium(I1) complexes.…”
