2 three pairs of F atoms in SF6, and the four pairs of Cl atoms related by the inversion operation have been denoted with subscripts 1,2, 3, and 4. You might remark, "Wait a minute! The 6 F in SF6 and 8 Cl in Re2Cl82-are all equivalent." That is correct, but the inversion, operation only relates pairs of atoms, or the unique sulfur atom to itself.
