Preferred Label : eighteen-electron rule;
IUPAC definition : An electron-counting rule to which an overwhelming majority of stable diamagnetic
transition metal complexes adhere. The number of nonbonded electrons at the metal
plus the number of electrons in the metal-ligand bonds should be 18. The 18 electron
rule in transition metal chemistry is a full analogue of the 'Lewis octet rule'.;
