Silver nitride is an inorganic chemical compound of silver from the group of nitrides .

Extraction and presentation

Silver nitride can be obtained by reacting silver (I) oxide with ammonia in ethanol .

properties

Silver nitride is a black, flaky solid that is sparingly soluble in cold water. It is soluble with decomposition in dilute mineral acids . An explosive reaction occurs with concentrated acids . Slow decomposition begins at 25 ° C in air, from a temperature of around 165 ° C the decomposition takes place explosively. The connection is very sensitive to mechanical influences, even when it is wet. Silver nitride has a face-centered cubic crystal structure and an enthalpy of formation of +199.1 kJ / mol. The crystal lattice (a = 4.369 Å) is formed by the face-centered cubic arrangement of the silver atoms, in whose octahedral gaps the nitrogen is located.
