Description

technical field [0001] The invention belongs to the technical field of organometallic chemistry, and in particular relates to a nested carborane-containing organometallic compound crystal and a preparation method thereof. Background technique [0002] Thanks to Li 2 E. 2 C 2 B 10 h 10 (E=S, Se) can act as a bidentate ligand to react with an organometallic reagent to form an organometallic compound containing a chalcogen-containing carborane. This type of compound not only has good chemical stability, solubility and crystallization properties, but also has aromaticity due to the five-membered metal heterocyclic ring with a nearly planar structure, and can be used as a model compound to study various organometallic chemical reactions. (eg: Meng X, Wang F S, Jin G X. Coord. Chem. Rev., 2010, 254, 1260; Hu J R, Wen J L, Wu D H, et al. Organometallics, 2011, 30, 298; Xie Z. Coord .Chem.Rev., 2006, 250, 259; Jin G X.
