Do ionic compounds have intermolecular forces?

Homework Statement

Do ionic compounds such as NaCl and K₂O have intermolecular forces?

2. The attempt at a solution
I got stuck conceptually. NaCl and K₂O are ionic compounds. Their basic unit is formula units. They are not molecular compounds. Ionic compounds are held together by electrostatic forces. So they don't have intermolecular forces?

Technically there is no such thing as a molecule of an ionic compound (unless we are talking about some exotic conditions, where they can be gaseous).

They don't have intermolecular forces. One more question: do metallic atoms have dispersion forces? In the textbook by Tro, "Since all atoms and molecules have electrons, they all have dispersion forces."
