Problem: A particular form of cinnabar (HgS) adopts the zinc blende structure shown. The length of the unit cell side is 5.852 Å. The mineral tiemmanite (HgSe) also forms a solid phase with the zinc blende structure. The length of the unit cell side in this mineral is 6.085 Å. What accounts for the larger unit cell length in tiemmanite?

🤓 Based on our data, we think this question is relevant for Professor Thompson's class at SHSU.

Problem Details

A particular form of cinnabar (HgS) adopts the zinc blende structure shown. The length of the unit cell side is 5.852 Å. Zn and S touch on a diagonal. The structure has a face-centered cubic lattice; a cube with lattice points at the corners and in the center of each face. The structure shows a cube with S as the corners (lattice points are in the center of each corner S). Layers of S alternate with layers of Zn.

The mineral tiemmanite (HgSe) also forms a solid phase with the zinc blende structure. The length of the unit cell side in this mineral is 6.085 Å. What accounts for the larger unit cell length in tiemmanite?
