5,lO-Seco-steroida containing a ten-membered ring (2) (instead of the two fused six-membered rings A and B) (e.g. I and II on Scheme 1) represent a suitable eubetrate for the study of truuunmilar reactivity in a medim-aired ring sytatem, because of the rel&ive rigidity of the general steroid framewo

## Abstract Several complexes of tropylium (**1**) with anions are optimized at the RI‐MP2(full)/6‐31++G\*\* level of theory. This binding unit can interact very favorably with anions, and it combines the strength of the electrostatic interaction with the directionality of the anion–π interaction.
