Synthesis and Crystal Structure of the Zinc Borate Zn3B4O9

Abstract

AbstractThe new zinc borate Zn3B4O9 was synthesized at high‐pressure/high‐temperature conditions of 10 GPa and 1173 K in a Walker‐type multianvil pressure device. It crystallizes in the space group P (no. 2) with a=5.5028(2) Å, b=6.7150(3) Å, c=7.8887(3) Å, α=83.99(1)°, β=73.38(1)°, γ=74.75(1)°, V=269.35(2) Å3, and two formula units (Z=2) per unit cell. The structure was confirmed via single‐crystal X‐ray diffraction. Zn3B4O9 can be synthesized phase pure, which is shown with a Rietveld refinement. IR‐spectroscopic data of a powder sample were collected.
