“…We report that treatment of [M(Tren(DMBS))(I)] (M = U, 1; Th, 2; Tren(DMBS) = {N(CH(2)CH(2)NSiMe(2)Bu(t))(3)}(3–)) with NaN(3) or KN(3), respectively, affords very rare examples of actinide molecular square and triangle complexes [{M(Tren(DMBS))(μ-N(3))}(n)] (M = U, n = 4, 3; Th, n = 3, 4). …”

“…Herein, we report a rare organosodium monomeric complex, namely, [Na(CH(2)SiMe(3))(Me(6)Tren)] (1-Na) (Me(6)Tren: tris[2-(dimethylamino)ethyl]amine) stabilized by a tetra-dentate neutral amine ligand Me(6)Tren. …”

“…For comparison, the coordination chemistry of a tetra-dentate tris-[2-(dimethylamino)ethyl]amine (Me(6)Tren) ligand was also studied. This work defines the available coordination modes of two multidentate amine ligands (DETAN and Me(6)Tren), guiding future applications of these ligands for pursuing highly reactive and elusive s-block and rare-earth metal complexes.…”

“…Moreover, we find that external Lewis base ligands, namely tris[2-(dimethylamino)ethyl]amine (Me(6)Tren) or 2,2,2-cryptand, can exert a level of reducing selectivity by preferably binding to Li(+) (Me(6)Tren) or K(+) (2,2,2-cryptand), hence pushing the electron to the other cation.…”

“…In comparison, the Me(6)Tren ligand features more robust coordination, with the sidearms less likely to undergo the decoordinating–coordinating equilibrium. …”
