What is the electron domain geometry about phosphorus in the hexafluorophosphate anion (pf6-) g?

Electron domain geometries are linear, trigonal planar, tetrahedral, trigonal bipyramidal, or octahedral. For PF6 - its electron domain geometry is an octahedral, its molecular geometry is also octahedral. Octahedral domain geometry is where six atoms are symmetrically arranged around a central atom.
