What Is The Crystal Structure Of Silver Selenide?

Silver selenide (Ag2Se) has a cubic crystal structure, specifically a rock salt structure. In this structure, each silver ion (Ag+) is surrounded by six selenium ions (Se2-) arranged in an octahedral configuration, and vice versa for the selenium ions. The lattice parameter, or the distance between adjacent ions, for Ag2Se is 5.991 angstroms.

Overall, the crystal structure of silver selenide can be described as a three-dimensional array of cations (silver ions) and anions (selenium ions) held together by electrostatic attraction due to their opposite charges. This results in the formation of a rigid and ordered crystalline material with well-defined physical properties.
