Abstract
AlB4O6N, Al0.97Cr0.03B4O6N, and Al0.83Cr0.17B4O6N are the first representatives of the recently established structure-family of oxonitridoborates containing Al3+. These compounds are isotypic to CrB4O6N and are synthesized in a multi-anvil press under high-pressure/high-temperature conditions of 7.0 GPa/1350 °C. Structural refinement by single-crystal X-ray diffraction shows that they crystallize in the space group P63mc (no. 186) with two formula units per cell. Detailed characterization including high-temperature X-ray powder diffraction (HT-XRD), electron probe microanalysis (EPMA), measurements of second harmonic generation (SHG), hardness, photoluminescence properties, vibrational spectroscopy, and band structure calculations reveal intriguing physicochemical properties that strongly resemble the famous material ruby.
