KSc(HPO 4 ) 2 was obtained by hydrothermal synthesis. The crystal structure was determined from single‐crystal X‐ray data: orthorhombic, space group Pnma (No. 62), a = 14.5095(10), b = 5.4260(4), c = 8.4882(5) Å, V = 668.26(8) Å 3 and Z = 4. The crystal structure of KSc(HPO 4 ) 2 represents a new structure type containing twelve‐ and four‐membered rings forming channels along [010] built of alternating ScO 6 octahedra and HPO 4 2− groups. Potassium ions reside within the twelve membered ring channels.
