Statistical analysis of PN clusters in Mo/VFe protein crystals using a bond valence method toward their electronic structures

“…The bond valence method was rst used to analyze inorganic crystal structures [32][33][34][35][36] and was gradually applied in other elds. [37][38][39][40][41] It can be traced back historically to a proposal by Pauling. 42 It is a classic and valid approach for assessing the charge between a metal atom and its bound coordinated atoms, and has proved an effective method to evaluate the electron density in a delocalized system 43 and the oxidation states of metals in a metalloprotein.…”
