High-pressure synthesis and characterization of the non-centrosymmetric scandium borate ScB6O9(OH)3

The non-centrosymmetric scandium borate ScB (OH) was obtained through a high-pressure/high-temperature experiment at 6 GPa and 1473 K. Single-crystal X-ray diffraction revealed that the structure is isotypic to InB (OH) containing borate triple layers separated by scandium layers. The compound cryst...

Summary:The non-centrosymmetric scandium borate ScB (OH) was obtained through a high-pressure/high-temperature experiment at 6 GPa and 1473 K. Single-crystal X-ray diffraction revealed that the structure is isotypic to InB (OH) containing borate triple layers separated by scandium layers. The compound crystallizes in the space group 2 with the lattice parameters  = 38.935(4),  = 4.4136(4), and  = 7.6342(6) Å. Powder X-ray diffraction and vibrational spectroscopy were used to further characterize the compound and verify the proposed structure solution.
