Redetermination of Fe(2)[BP(3)O(12)]

Area of Science:

• Inorganic Chemistry
• Solid-State Chemistry
• Crystallography

Background:

• Previous synthesis of Fe(2)[BP(3)O(12)] yielded microcrystalline material.
• The crystal structure was previously refined using powder X-ray diffraction data in space group P3.

Purpose of the Study:

• To grow single crystals of anhydrous diiron(III) borotriphosphate, Fe(2)[BP(3)O(12)].
• To determine the accurate crystal structure and space group of the title compound using single-crystal X-ray diffraction.

Main Methods:

• High Temperature Solution Growth (HTSG) method for single-crystal synthesis.
• Single-crystal X-ray diffraction for structural determination.

Main Results:

• Single crystals of Fe(2)[BP(3)O(12)] were successfully obtained.
• The correct space group was identified as P6(3)/m, differing from the previously reported P3.
• The three-dimensional structure comprises FeO(6) octahedra, BO(3) groups, and PO(4) tetrahedra.

Conclusions:

• The single-crystal study provides a precise structural description of Fe(2)[BP(3)O(12)].
• The findings correct and refine the understanding of this borotriphosphate compound's crystal structure and symmetry.
