In the title molecule, C17H12F2O3, the dihedral angle between the benzene rings is 8.6 (2)°. In the crystal, two pairs of O—HO hydrogen bonds connect the molecules into inversion dimers. In addition, weak C—HF hydrogen bonds link the dimers into a two-dimensional network parallel to (10-4). The carbonyl O atom is an acceptor for two weak intramolecular hydrogen bonds.

In the title compound, C18H21N2O6P, the dihedral angle between the benzene and phenyl rings is 85.1 (2)°. In the crystal, molecules are linked via pairs of N—HO(=P) hydrogen bonds, forming inversion dimers with graph-set notation R22(10). One of the ethyl groups is disordered over two sets of sites, with occupancies 0.746 (11) and 0.254 (11).
