Abstract

KCd(N3)3 · H2O crystallizes in space group Pnma with a = 11.991(2), b = 3.712(1), c = 17.292(2) Å and Z = 4. K2Cd(N3)4 crystallizes in space group C2/m with a = 14.272(2), b = 3.787(1), c = 8.887(2), β = 92.83(2)° and Z = 2.

The structures have been determined from single crystal X-ray data. The final R-values are 0.074 and 0.063 respectively.

In both structures cadmium is surrounded octahedrally by six azide groups; the Cd(N3)6-octahedra share edges. Potassium is coordinated by seven azide groups and two water molecules in KCd(N3)3 · H2O and by eight azide groups in K2Cd(N3)4. In both structures all azide groups are approximately parallel, with mean N – N = 1.17(5) Å.
