Abstract: | Ternary System KN3? Ca(N3)2? H2O at 298 K The ternary system KN3? Ca(N3)2? H2O has been investigated at 298 K by means of solubility measurements and x-ray methods. A complex alkali-alkaline earth azide hydrate with the composition K2Ca(N3)4 · 4 H2O was crystallized and the stability condition defined. Lattice parameters were determined by x-ray single crystal techniques. K2Ca(N3)4 · 4 H2O crystallizes orthorhombic, a = 1876.9, b = 1094.4, c = 613.9 pm, N = 4, space group Ccca. |
