The crystal structure of the co-crystal of aqua-tri-fluorido-boron with two ethyl-ene carbonate (systematic name: 1,3-dioxolan-2-one) mol-ecules, BFHO·2OC(OCH), was determined by low-temperature single-crystal X-ray diffraction. The co-crystal crystallizes in the ortho-rhom-bic space group 222 with four formula units per unit cell. The asymmetric unit consists of an aqua-tri-fluorido-boron mol-ecule and two ethyl-ene carbonate mol-ecules, connected by O-H⋯O=C hydrogen bonds. This crystal structure is an inter-esting example of a superacidic BFHO species co-crystallized with an organic carbonate.
三水合三氟硼酸与两个碳酸亚乙酯（系统名称：1,3 - 二氧戊环 - 2 - 酮）分子形成的共晶体（BFHO·2OC(OCH)）的晶体结构通过低温单晶X射线衍射测定。该共晶体在正交晶系空间群222中结晶，每个晶胞含有四个化学式单元。不对称单元由一个三水合三氟硼酸分子和两个碳酸亚乙酯分子组成，通过O - H⋯O = C氢键相连。这种晶体结构是超酸性BFHO物种与有机碳酸盐共结晶的一个有趣例子。
