Dj. Burkey et Tp. Hanusa, SYNTHESIS AND CHARACTERIZATION OF THE ENCAPSULATED STANNOCENES [(C3H7)(3)C5H2]SN-2 AND [(C3H7)(4)C5H]SN-2, Organometallics, 14(1), 1995, pp. 11-13
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-sensit
ive oil, respectively; their physical properties mirror those of alkal
ine-earth metallocenes containing these ligands. The X-ray crystal str
ucture of [(C3H7)(4)C5H]Sn-2 reveals a bent-metallocene geometry close
ly related to that of [(C3H7)(4)C5H]Ca-2
