Using the Molecule Definition Utility found in both "Metallic Crystal
Structures and Crystallography" and "Ceramic Crystal Structures" modules of
VMSE, located on the book's web site [www.wiley.com/college/callister (Student
Companion Site)], generate (and print out) a three-dimensional unit cell for
lead oxide, \(\mathrm{PbO}\), given the following: (1) The unit cell is
tetragonal with \(a=0.397 \mathrm{nm}\) and \(c=0.502 \mathrm{nm},(2)\) oxygen
atoms are located at the following point coordinates:
$$\begin{array}{ll}
000 & 001 \\
100 & 101 \\
010 & 011 \\
110 & 111 \\
\frac{1}{2} \frac{1}{2} 0 & \frac{1}{2} \frac{1}{2} 1
\end{array}$$ and (3) \(\mathrm{Pb}\) atoms are located at the following point
coordinates: $$\frac{1}{2} 00.763 \quad 0 \frac{1}{2} 0.237$$ $$\frac{1}{2}
10.763 \quad 1 \frac{1}{2} 0.237$$
