Synthesis and single crystal X-ray structure of the tetragonal tungsten bronze Pb0,91K1,72Li1,46Nb5O15

Crystals of Pb 0.91K 1.72Li 1.46Nb 5O 15, belonging to tetragonal tungsten bronze materials, were grown by the slow cooling technique, and characterized by means of single crystal X-ray diffraction: the structure was solved in the P4bm tetragonal space group, with the following unit cell parameters: a = 12.548(5), c = 4.042(5) Å, V = 636.4(9) Å 3
