The title compound, [ReO2(C6H7N)4]PF6, contains octa­hedral [ReO2(4-Mepy)4]+ cations (4-Mepy is 4-methyl­pyridine) and PF6 − anions. Both the cation and the anion reside on special positions, the Re atom on a crystallographic center of inversion and the P atom on a C 2 axis parallel to the b axis. The ReV atom in the cation exhibits an octa­hedral coordination geometry with two O atoms in the apical positions and four N atoms of the 4-Mepy ligands in the equatorial plane. The Re=O and Re—N bond lengths fall in the typical ranges of trans-dioxidorhenium(V) complexes.
