There are two molecules in the asymmetric unit of C10H6F12O4 that diff
er primarily in their packing and hydrogen bonding. The molecules are
linked in groups of four by the hydrogen bonding between the hydroxyls
about an inversion center. In one of the independent molecules, one h
ydroxyl is a hydrogen donor and the other is an acceptor, while in the
second molecule the hydroxyls act as both donor and acceptor.
