Synthesis and Characterization of the Encapsulated Stannocenes [(C3H7)3C5H2]2Sn and [(C3H7)4C5H]2Sn
摘要:
The encapsulated stannocenes [(C3H7)(4)C5H]Sn-2 and [(C3H7)(3)C5H2]Sn-2 are isolated as an, air-stable, high-melting solid and an air-sensitive oil, respectively; their physical properties mirror those of alkaline-earth metallocenes containing these ligands. The X-ray crystal structure of [(C3H7)(4)C5H]Sn-2 reveals a bent-metallocene geometry closely related to that of [(C3H7)(4)C5H]Ca-2
