First it must be cyclic Second every atom around the ring must have an available p-orbital. Atom cluster compounds including metal clusters have been unwittingly used by humans since antiquity.
However removal of three electrons requires over 6700 kJ mol 1 and this is so high that it precludes compounds that are strictly ionic.

Third the number of electrons in the pi system must be 2 6 10 14 18 or a higher number in the set that.
The rule is based on the fact that the valence shells of transition metals consist of nine valence orbitals one s orbital three p orbitals and five d orbitals which collectively can accommodate 18.

1322 Bonding in boron compounds.
With the electronic structure of the boron atom being 1s 2 2s 2 2p 1 it might be expected that boron would lose three electrons to give compounds that contain B 3 ions.
Oxygen evolution reaction OER is a limiting reaction in the process of generating molecular oxygen through chemical reaction such as the oxidation of water during oxygenic photosynthesis electrolysis of water into oxygen and hydrogen and electrocatalytic oxygen.
The oldest artificially produced metal cluster may be calomel Hg 2 Cl 2 which was known in India already in the 12th century.
Enthalpies of sublimation of organic and organometallic compounds.
Johnson group journal blog launched.
In organometallic chemistry there is something known as the 18-electron rule which essentially suggests that stable complexes have an electron count of 18A general discussion of electron counting is beyond the scope of the current answer but in the specific case of ceFeCO5 we have ceFe0 which accounts for 8 electrons and five ceCO ligands.
The discovery of ferrocene in 1951 and its structural elucidation by two separate research groups the following year marked the birth of contemporary organometallic chemistry.
