I agree that most media aim to create such click-bait titles but I think in this particular case the word "structure" comes from the original paper [0] so there isn't much the author could do. Our language is too slow to invent new words for newly discovered elements of the universe and scientists have to draw words from the common language for it to be easily interpretable.
