The crystal structure of Y 2 P 4 O 13 from X-ray powder diffraction data

The crystal structure of Y 2 P 4 O 13 from X-ray powder diffraction data Abstract The crystal structure of Y 2 P 4 O 13 has been determined from X-ray powder diffraction data. Y 2 P 4 O 13 crystallizes in the orthorhombic space group C 222 1 (No. 20) with a = 17.2817(7) Å, b = 6.9823(4) Å, c = 8.5391(3) Å, V = 1030.38(8) Å 3 , and Z = 4. The structure has been solved by direct methods using EXPO program and refined by FULLPROF package. The final R Bragg value was 9.1%. The tetraphosphate anion has the point group 2 symmetry. The yttrium atom is seven-coordinated forming strongly distorted octahedron with one bifurcated vertex. There are infinite chains of oxygen-bridged ittrium atoms running parallel to the b axis and linked together by the tetraphosphate anions with formation of three-dimensional network. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Zeitschrift für Kristallographie - Crystalline Materials de Gruyter

Abstract

Abstract The crystal structure of Y 2 P 4 O 13 has been determined from X-ray powder diffraction data. Y 2 P 4 O 13 crystallizes in the orthorhombic space group C 222 1 (No. 20) with a = 17.2817(7) Å, b = 6.9823(4) Å, c = 8.5391(3) Å, V = 1030.38(8) Å 3 , and Z = 4. The structure has been solved by direct methods using EXPO program and refined by FULLPROF package. The final R Bragg value was 9.1%. The tetraphosphate anion has the point group 2 symmetry. The yttrium atom is seven-coordinated forming strongly distorted octahedron with one bifurcated vertex. There are infinite chains of oxygen-bridged ittrium atoms running parallel to the b axis and linked together by the tetraphosphate anions with formation of three-dimensional network.
