Lithocene
Web1 aug. 1997 · Ab initio and density functional theory (DFT) calculations using the GAUSSIAN 94 program have been performed to investigate the molecular structure of the lithocene anion at the 3–21G, 6–31G, 6–31 + G, 6–31G ∗, and 6–31G ∗∗ basis sets. This anion is found to be most stable at the D 5d symmetry. The results show that DFT calculations at … Web9 jan. 1996 · While, the lithocene anion (Cp 2 Li-) can simply be generated by reacting 2 equiv of CpLi with PPh 4 Cl in THF, the attempted synthesis of the sodocene anion …
