The chemical formula, BaB2O4, doesn't correspond with the image I see. Barium is green, boron is pink and oxygen is red.

Wiki Barium borate

No clue about crystals but willing to learn the basics.

The stochiometric formula doens't tell you more than the relative amount of substance of Ba, B and O, but nothing about the structure. Do you doubt the relative proportions of the elements in this compound?
 
No doubt here. My prior experience had me looking at reactions and chemicals in aqueous environments. This one was not like the others and I thought I would ask about it. Organic chemistry ii was finished last fall by myself so barium is new to me.

How does barium influence boron and oxygen to form into a ring structure while being a spectator cation during a solid state? Why do they form on top of each other in triplets?
 
Are you sure that rings of BO3 units don't occur also in solution?
