摘要：

A highly non‐aromatic structure is exhibited by the free germacyclopentadienide ion (shown on the right) in the Li([12]crown‐4)2 salt. The angle between the C4Ge plane and the GeSi bond is 100.1°. Calculations at the RHF level of theory on (C4H4GeSiH3)− accurately reproduce the observed geometrical parameters, and predict that the analogous Si and Sn derivatives would also have highly pyramidalized structures.
