Synthesis and Crystal Structure of Vanadium(III) Borophosphate, V 2 [B(PO 4 ) 3 ] By reaction of boron phosphate, BPO 4 , and vanadium(IV)‐oxide, VO 2 , at 1050 °C a hitherto unknown vanadium(III)‐borophosphate is formed. Its composition was found to be V 2 BP 3 O 12 , its structure was elucidated by single crystal X‐ray diffraction, the cell parameters are: a = b = 13.9882Å; c = 7.4515Å; α = β = 90°, γ = 120°; Z = 6; space group: P6 3/m. Noteworthy features of the structure are V 2 O 9 units (two V III O 6 octahedra connected via their faces) and isolated trisphosphatoborate groups, B(PO 4 ) 3 . By shared oxide ions, the aforementioned groups are interconnected, thus forming a three dimensional network. The structural relation between the title compound and an analogous chromium compound is discussed.
