Die Kristallstruktur eines Kalium-Strontium-Azidhydrates K2,24Sr1,34(N3)4,92(H2O)6,l6
Abstract
Potassium strontium azidehyclrate forms a series of solid solutions. Crystals with the composition defined in the title have been investigated using three-dimensional photographic x-ray data. The crystals are orthorhombic, a = 6.398 Å, b = 10.915 Å, c= 6.263 Å. The structure was solved by Patterson and Fourier techniques, and refined by least-squares method based on 291 independent X-ray reflections to an R value of 0.085. The cations are not equally distributed among the twofold positions 000 and ½0½ within the space group C222. Each cation position has eight neighbours which form a non regular antiprism. The coordination polyhedra contain N atoms and water which are distributed at random. The azicle ions are linear and symmetric, N—N = 1.175Å.
