WebEffective Coordination Number Features5 Effective coordination number of an atom is defined as: 𝐶𝑁 𝑒𝑓𝑓 = (∑ 𝑛 𝐴 𝑛) 2 ∑ 𝐴 2 𝑛 (3) where𝐴𝑛 is the area of face 𝑛in its Voronoi cell. The maximum, minimum, mean, and mean absolute deviation in coordination number are calculated as features. Structural ... WebFeb 14, 2024 · The coordination number of an ion (also called its ligancy) in a crystal lattice structure is the number of immediate neighbors it has possessing the opposite charge. The anion to cation ratio must be reflected in this coordination number, which can influence the color of the compound. ... This central atom is geometrically associated …
