CIF Files

CIF files contain crystallographic information, allowing you to electronically manipulate three dimensional structures. Download the CIF data files and open them in a compatible program, such as Mercury. These two files relate to figure 6.20 and figure 6.21, on page 144 in Foundations of Molecular Structure Determination 2e.
