What is NaSc~3~[HPO~3~]~2~[HPO~2~(OH)]~6~: Synthesis, Crystal Structure, and Thermal Decomposition about?

## Abstract NaSc~3~[HPO~3~]~2~[HPO~2~(OH)]~6~ was prepared by use of a phosphorus acid flux route. The crystal structure was determined from single‐crystal X‐ray diffraction data: triclinic, space group __P__$\bar{1}$ (No. 2), __a__ = 7.4507(11) Å, __b__ = 9.6253(17) Å, __c__ = 9.6141(16) Å, __α__ = 115.798(4)°, __β__ = 101.395(4)°, __γ__ = 101.136(3)°, __V__ = 577.29(16) Å^3^ and __Z__ = 1. The crystal structure of NaSc~3~[HPO~3~]~2~[HPO~2~(OH)]~6~ contains two kinds of phosphate(III) groups: HPO~3~^2–^ and HPO~2~(OH)^–^. Phosphate(III)‐tetrahedra, NaO~6~ and ScO~6~ octahedra together form a (3,6)‐connected net. During heating hydrogen and water are released and Sc[PO~3~]~3~ is formed as the main crystalline decomposition product.
