Silver azide is the
chemical compoundwith the formula AgN3. This colourless solid is a well known explosive.
Preparation, structure, decomposition
X-ray crystallography shows that AgN3 is a coordination polymer with
square planarAg+ coordinated by four azide ligands. Correspondingly, each end of each azide ligand is connected to a pair of Ag+ centers. The structure consists of two-dimensional AgN3 layers stacked one on top of the other, with weaker Ag-N bonds between layers. The coordination of Ag+ can alternatively be described as highly distorted 4 + 2 octahedral, the two more distant nitrogen atoms being part of the layers above and below.

AgN3, like most heavy metal azides, can be dangerously explosive.
