<unk>  (chemical name: 4-(1-hydroxy-1,3-dihydro-2,1-benzoxaborol-5-yl)oxybenzonitrile) is a member of the class of benzoxaboroles characterized by the presence of a boronic acid hemiester with a phenolic ether and a nitrile.<unk>  crystallizes into two polymorphs that differ in the conformation of the oxaborole ring. A cocrystal with 4,4'-bipyridine has been prepared and studied by X-ray crystallography.
