Position of importance : The relative apicophilicity of two substituents linked by a carbon atom to a pentacoordinate phosphorus center such as that in compounds 1 was determined based on the equilibrium ratio of pseudorotamers ( 1 A and 1 B ) in solution. A distinct solvent effect on the relative apicophilicity and a novel phenomenon in which two different pseudorotamers cocrystallized in the same single crystal were observed.
