Abstract

Single crystals of La₂NaTaO₆ were grown out of a reactive high-temperature hydroxide melt. The structure was determined by single crystal X-ray diffraction. La₂NaTaO₆ adopts the monoclinically distorted double perovskite structure type with general formula A2BB′O6, where tantalum atoms are located on the B′ site. La₂NaTaO₆ crystallizes in the monoclinic space group P21/n with a=5.6904(2) Å, b=5.9824(2) Å, c=8.1423(2) Å and β=90.8650(10)°⋅ An optical bandgap of 4.5 eV was estimated from the UV–vis diffuse reflectance spectrum.
