A Water Adduct of Tris(pentafluorophenyl)borane: (C₆F₅)₃B(OH₂)-Dioxane-CH₂Cl₂ (1/1/1)

The dichloromethane solvate of the 1:1 aquatris(pentafluorophenyl)borane-dioxane adduct, [B(C₆F₅)₃(H₂O)].C₄H₈O₂.CH₂Cl₂, is a water complex of tris(pentafluorophenyl)borane, which was crystallized from dioxane-methylene chloride solution. The water molecule was carried in either through improperly dried solvent or during the process of crystallization. The structure contains one dioxane and one CH₂Cl₂ molecule per formula unit. Two dioxane molecules form hydrogen bridges to the water molecule and also bridge between two different adduct moieties, so that an infinite chain of borane-water adducts and dioxane molecules is created.
