Abstract: The reaction of 2, 6-iPr2C6H3NHSiMe3 with Tb(CH2SiMe3)3(THF)2 in benzene at room temperature afforded a binuclear terbium complex Tb2{μ-CH2SiMe2NC6H3iPr2-2, 6}3(THF)3. X-ray diffraction revealed that Tb atoms were bridged by three methylene units. One Tb atom was six-coordinated by two nitrogen atoms, three methylene carbons, and one THF molecule, while the other Tb atom was six-coordinated by one nitrogen atom, three methylene carbons, and two THF molecules. Both Tb atoms adopted a distorted trigonal prism geometry.
