Barium Borate- beta BBO crystals (what am I looking at?)

In summary, The conversation is discussing the chemical formula of Barium borate, BaB2O4, and its structure. The speaker is curious about how barium influences the formation of a ring structure with boron and oxygen, and why they form on top of each other in triplets. The expert suggests that the stoichiometric formula only provides information about the relative amounts of Ba, B, and O, but not the structure itself. The speaker also mentions their prior experience in aqueous environments and completing Organic Chemistry II, making barium a new topic for them. The expert questions if rings of BO3 units could also occur in solution.

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

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?

Barium borate-beta BBO crystals, also known as beta-barium borate crystals, are a type of nonlinear optical crystal that is commonly used in laser technology. The chemical formula, BaB2O4, may not correspond with the image you see because the image may be a representation of the crystal structure rather than the individual atoms. The colors you mention are likely used to indicate the different elements present in the crystal. Barium, boron, and oxygen are all important components of this crystal and contribute to its unique properties. I would recommend researching the crystal structure and properties of barium borate-beta BBO crystals to gain a better understanding of what you are looking at. This can help you appreciate the significance and potential applications of this material in scientific research and technological advancements.
