The cluster expansion coefficients, at the heart of Didier de Fontaine’s research, may be formally related to local N-body potentials. Recent developments in deriving analytic many-body bond-order potentials (BOPs) are shown to predict reliable structural trends across the sp-valent elements, thereby making BOPs a valuable tool in the understanding and derivation of cluster expansion coefficients.
