Explanation:

Iron has two different crystal structures at atmospheric pressure: the body centered cubic (bcc) and the face centered cubic (fcc). ... The boiling point of iron is about 3300K. A third form of iron, which has the hexagonal close packed (hcp) structure, can be stabilized under high pressures.
