Bonding and Atomic Spacing

By using the geometrical constants of the stmcture of the interstitial monocarbides and of the individual atoms, Kisly has proposed a relative contribution of each bonding component, ionic and covalent, as shown in Table3.10.[i51 

In this table, the measured length of the metal-carbon bond of each monocarbide is compared to the sum of the covalent radii of the metal and carbon atoms. The change, AC, is expressed in percentage. As can be seen.
