===Ionic crystal structures===
In 1929, Pauling published [[Pauling's rules|five rules]] which help to [[crystal structure prediction|predict]] and explain [[crystal structure]]s of [[ionic compound]]s.<ref>{{Cite journal |last=Pauling, Linus |author-link=Pauling L |year=1929 |title=The principles determining the structure of complex ionic crystals |journal=J. Am. Chem. Soc. |volume=51 |issue=4 |pages=1010–1026 |doi=10.1021/ja01379a006|bibcode=1929JAChS..51.1010P }}</ref><ref name=Pauling1960/> 
These rules concern (1) the ratio of cation radius to anion radius, (2) the electrostatic bond strength, (3) the sharing of polyhedron corners, edges and faces, (4) crystals containing different cations, and (5) the rule of parsimony.{{citation needed|date=August 2023}}
