Abstract
The syntheses and the results of unit‐cell determinations ofBa3V4O13 and the two forms (low‐ and high‐temperature) of Ba3P4O13 are presented. Ba3V4O13 crystallizes in the monoclinic system, space group Cc or C2/c with unit‐cell dimensions a=16.087, b=8.948, c=10.159 (x10nm), β=114.52° Low‐Ba3P4O13 crystallizes in the triclinic system, space group P1 or P1 with unit‐cell dimensions a=5.757, b=7.243, c=8.104 (x10 nm) α=82.75°, β=73.94°, γ=70.71°. Low‐Ba3P4O13 transforms at 870°C into high‐Ba3P4O13 which crystallizes in the orthorhombic system, space group Pbcm (No. 57) (or Pbc2, No. 29) with unit‐cell dimensions a =7.107, b=13.883, c=19.219 (x10 nm). No relations have been found between the structures of the tribarium tetravanadate and the tribarium tetraphosphate.
