A two dimensional refinement of a (1,6) phase intergrowth tungsten bronze (K[sub x]WO[sub 3]) structure was attempted. The intensities of diffracted x-ray radiation from single-crystal samples were recorded and measured. The unit cell shape was confirmed as orthorhombic with measured lattice constants a = 62.13 (1) A, b = 7.339 (2) A, c = 7.77 (1) A. The examination: of a photographic record of “reflections” and measured intensity data indicate a unit cell symmetry corresponding to either Pn- nm or Pnn2. A three dimensional least-squares refinement of a model structure was attempted, but the complexity of the problem at hand and lack of time allowed for only a two dimensional refinement. The results are discussed in this paper.
