Boron nitride

Some ionic bond strength component in contrast to carbon structures. Very strong (comparably to covalent) dative bonding.

h-BN

Isostructural to graphite.
Most common in literature as of 2025.
In stark contrast to graphite a very good insulator.

c-BN cubic boron nitride (quingsongite)

Isostructural to diamond and zincblende structure.
Less common in literature as of 2025.

Interesting in seamless crystal structure transitions to and from diamond.

• Either for structural mechanical reasons (intentional bending by slight size differences).
• Or for electronic property reasons.

One period up analogous compound would be aluminum phosphide. Highly toxic.
The two mixed period variants:

• Aluminum nitride (attacked by water if not sealed, hexagonal wurzite structure lower engery)
• Boron phosphate (very stable and hard)

sp3-h-BN

Isostructural to lonsdaleite and wurzite structure.
Exotic in literature as of 2025.
