Abstract

Abstract : The novel dysprosium borate DyB5 O8 (OH)2 was synthesized in a Walker‐type multianvil apparatus at a pressure of 2.5 GPa and a temperature of 673 K. Single‐crystal diffraction data provided the basis for the structure solution and refinement. The compound crystallizes in the acentric monoclinic space group C 2 (no. 5) with the lattice parameters a = 7.9288(5), b = 4.4009(3), c = 9.3409(8) Å, and a monoclinic angle of 113.76(1)°. Generally, DyB5 O8 (OH)2 is comprised of a layer‐like structure consisting of corner sharing [BO4 ] 5– tetrahedra forming dreier and sechser rings, and eightfold coordinated dysprosium cations. Further characterizations were performed by IR and luminescence spectroscopy as well as high‐temperature X‐ray diffraction. Abstract : Dysprosium borate DyB5 O8 (OH)2 was synthesized in a Walker‐type multianvil apparatus under high‐pressure/high‐temperature conditions. Made up of borate dreier and sechser rings, the dysprosium borate shows a layer‐like structure stacking along the c ‐axis. Characterization was done with single‐crystal X‐ray diffraction, high‐temperature X‐ray diffraction, infrared spectroscopy, and luminescence spectroscopy.
