Catching Wyckoff’s Phantom: The Peculiar Crystal Structure of Orthorhombic Cs[ICl2]
In their recent ZAAC contribution Jan Langwald, Antonio Frontera, and Mathias S. Wickleder tackled “Wyckoff's Phantom”, an elusive orthorhombic crystal polymorph of caesium dichloroiodate (Cs[ICl₂]-II) that evaded selective isolation and verification for roughly a century.
