摘要：

The complex [{1,3-[2,6-(i-Pr)(2)-C6H3N](2)(CH2)(3)}(2)ThCl][Li(THF)(4)] (1), containing two chelating amides, was prepared via straightforward halogen replacement of ThCl4(DME) with dilithium salt of 1,3-[2,6-(i-Pr)(2)C6H3NH](2)(CH2)(3.) Attempts to reduce this species were carried out with K(naphthalenide), affording an intermediate dark colored solution that slowly discolored and yielded colorless crystals of the tetravalent metallacyclic complex [{1,3-[2,6-(i-Pr)(2)-C6H3N](2)(CH2)(3)}{1,3-[2-(i-Pr)-6-(CH2CHCH2)C6H3N](2) (CH2)(3)}Th][Li(DME)(3)] (2). In this species, one hydrogen atom of one neighboring ligand methyl group was eliminated to form a metallacyclic structure.
