Abstract:The isostructural lanthanoid bismuth oxide oxidosilicates with the formula LnBiO[SiO4] (Ln = La and Gd) crystallize in the triclinic space group P with Z = 2 for both. Colorless single crystals were serendipitously obtained from the reaction of bismuth sesquioxide, bismuth trifluoride and the lanthanoid sesquioxides at 850 °C in unprotected torch‐sealed silica ampoules as SiO2 source. Their crystal structure features Ln3+ cations surrounded by eight oxygen atoms as distorted square antiprisms [LnO8]13–, which … Show more
