Crystal growth of La2NaTaO6: A new monoclinically distorted double perovskite
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.
