Synthesis and crystal structure of the first ternary tellurium borate TeB4O8

Monoclinic TeB4O8 was obtained in a Walker-type multianvil apparatus at 10 GPa and 1273 K from TeO2 and B2O3. It crystallizes isotypically to the compounds AnB(4)O(8) (An=Th, U) in the space group C2/c (Z=4) with the lattice parameters a=15.6978(8) angstrom, b=4.2284(2) angstrom, c=7.4305(4) angstrom, beta=114.78(1)degrees, and V=447.80(4) angstrom(3). Further, it has been characterized via X-ray diffraction experiments and IR spectroscopy.

Automated summary

Monoclinic TeB4O8 was synthesized at high pressure and temperature, and characterized by X-ray diffraction experiments and IR spectroscopy.
