What name is given to compounds that exist as giant repeating lattices?

1. Small molecules such as water exist and interact as separate units. 2. Compounds that exist as giant repeating lattice structures are called network structures instead. 3. Diamond, graphite and a sodium chloride crystal are all examples. 4. Metals also count as network structures, since a piece of copper is one huge lattice. _Source: Siyavula Physical Sciences Grade 10 (Everything Science, CC BY 4.0), Chapter 12: The particles that substances are made of_
