| Abstract: | Reaction of 1,3,5-trimethyl-1,3,5-triazacyclohexane (MeNCH2)3] with Os3(CO)12 in refluxing toluene results in C-H and C-N bond activation of the (MeNCH2)3 ligand to afford three amidino cluster complexes (μ-H)Os3(CO)10μ,η2-CH(NMe)2] (1), (μ-H)Os3(CO)9μ3,η2-CH(NMe)2] (2), and Os2(CO)6μ,η2-CH(NMe)2]2 (3). The controlled experiments show that thermolysis of 1 yields 2, and heating 2 in the presence of (MeNCH2)3 ligand produces 3. The molecular structures of 1 and 3 have been determined by an X-ray diffraction study. |
