The replacement of sp 2 C−R fragments by isolobal phosphorus atoms may cause a reversal of the order of the frontier orbitals on metallocenes (see scheme). Hexaphosphamanganocene 1 is a good example to demonstrate this effect, as it exhibits the ground state 2 A, not previously observed for manganocene derivatives. The spin‐density distribution of 1 mainly resembles a manganese d z 2orbital. In contrast to decamethylmanganocene, 1 is not Jahn–Teller active!
