Characterized by microwave spectroscopy after their formation in a supersonic jet, the axial and equatorial hydrogen bond conformers of the title complex were studied. The axial form—shown in the picture—has been found to be the most stable one. The experimental data are consistent with a C s symmetry for both conformers, in which linear hydrogen bonds lying in the symmetry plane bisect the C‐O‐C angle. The structure of tetrahydropyran subunit in the axial form was also determined and no significant structural distortion occurs upon complexation.
