The atoms of crystalline solid pack together into a
three-dimensional array of many small repeating units called
unit cells. The simplest of the unit cells are those that
have cubic symmetry, with atoms positioned at the corners of a
cube. Atoms can also be found in the sides (faces) of the cube, or
centered within the body of the cube. It is important to realize
that a unit cell is surrounded by other unit cells in every
direction. Therefore, face...

3. The ReO2 structure is cubic with one Re atom at each corner of the unit cell and one O atom on each unit cell edge midway between the Re atoms. a. Sketch this unit cell. b. Determine the coordination number of each cation and anion. c. Confirm that the stoichiometry is consistent with the structure. d. Determine the identity of the structure type that would be generated if a cation were inserted into the center of the ReOz structure.

Imagine a unit cell that consists of corner-centered atoms "A", body-centered atom "B", face-centered atoms "C", and edge-centered atoms "D". This would mean that the total parts of "A" would add to Blank 1 atom(s), the total parts of "B" would add to Blank 2 atom(s), the total parts of "C" would add to Blank 3 atom(s), and the total parts of "D" would add to Blank 4 atom(s). Assume that a crystal structure is made up...
