Apicophilicity is the relative preference of substituents to occupy the apical positions as opposed to the equatorial positions in trigonal bipyramidal (TBP) structures and is one of the fundamental properties of pentacoordinate compounds.

## Abstract Relaxation times, __T__, due to the dipolar mechanism of relaxation of ^31^P nuclei were determined for eight pairs of 1,3‐dithianes with P‐containing substituents at the anomeric carbon atom. The separation of dipole–dipole from the total spin–lattice relaxation could be applied for th
