In the title compound, C(18)H(23)O(4)P, the dihedral angle between the aromatic ring planes is 69.94 (14)°. Both ethyl side chains are disordered over two sets of sites, with occupancy ratios of 80:20 and 70:30. In the crystal, inversion dimers linked by pairs of O-H⋯O hydrogen bonds occur, leading to R(2) (1)(8) loops, and C-H⋯O and weak C-H⋯π inter-actions are also seen.

The title compound, C(12)H(19)O(4)P, has a distorted tetra-hedral geometry around the P atom. The molecules form dimers with R(2) (2)(10) ring motifs due to inter-molecular O-H⋯O hydrogen bonds. The double-bonded O atom of the phospho-nate group behaves as an acceptor and the hydr-oxy group acts as a donor. Both of the ethyl groups are disordered with occupancies of 0.55:0.45 and 0.725:0.275.

In the title compound, C(14)H(21)FNO(6)P, a staggered conformation about the central P-C bond occurs, with the oxo and hydroxyl groups occupying diagonally opposite positions. The crystal structure features supra-molecular chains mediated by O-H⋯O hydrogen bonds, which propagate in the a-axis direction. A C-H⋯O inter-action consolidates the chains. Disorder was resolved for one of the isopropyl...
