Statement 1 : Ortho boric acid crystal are hard and cannot be broken easily into the powder form.Statement 2 : In the solid state BOH3 units are hydrogen bonded together into two dimensional sheets.

In the solid state, the BOH3 units are hydrogen bonded together into two dimensional sheets with almost hexagonal symmetry. The layered are quite a large distance apart (3.18Ao) and thus the crystal breaks quite easily into very fine particles.
