As a general rule of thumb, compounds that involve a metal binding with either a non-metal or a semi-metal will display ionic bonding. The crystal is essential a single, macroscopic molecule with continuous chemical bonding throughout the entire structure. Because of the difficulty of building disordered models at the correct density with many boroxol rings, this view was initially controversial, but such models have recently been constructed and exhibit properties in excellent agreement with experiment.
