Abstract:
Planar hypercoordinate fluorine is rare due to the high electronegativity of F. A Zn5O5 framework stabilizes D5h F©Zn5O5- as a global minimum. The bonding is predominantly electrostatic with a minor covalent contribution. A detachment energy of 6.29 eV places the cluster in the superhalogen regime.
