title: trans-Tetra-kis(4-methyl-pyridine-κN)dioxidorhenium(V) hexa-fluorido-phosphate.
abstract: The title compound, [ReO(2)(C(6)H(7)N)(4)]PF(6), contains octa-hedral [ReO(2)(4-Mepy)(4)](+) cations (4-Mepy is 4-methyl-pyridine) and PF(6) (-) 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 Re(V) atom in the cation exhibits an octa-hedral 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.
