The Front Cover shows that owing to the overlap of the lone pairs, the through‐space σ‐effect enhances the ability of the O‐atoms to participate in hydrogen bonding interactions. This impressive effect is represented by the strong magnet that attracts the H‐atom of the C–H bond. More information can be found in the Full Paper by F. I. Zubkov, A. Frontera et al.
