Trapping an Ester Hydrate Intermediate in a π-Stacked Macrocycle with Multiple Hydrogen Bonds.

ABSTRACT: Ester hydrates, as the intermediates of the esterification between acid and alcohol, are very short-lived and challenging to be trapped. Therefore, the crystal structures of ester hydrates have rarely been characterized. Herein, we present that the mono-deprotonated ester hydrates [CH₃OSO₂(OH)₂]^-, serving as the template for the self-assembly of a π-stacked boat-shaped macrocycle (CH₃OSO₂(OH)₂)_0.67(CH₃OSO₃)_1.33@{[ClLCo^II]₆}·Cl₄·13CH₃OH·9H₂O (1) (L = tris(2-benzimidazolylmethyl) amine), can be trapped in the host by multiple NH···O hydrogen bonds. In the solution of CoCl₂, L, and H₂SO
