In the title compound, C30H48BNOP2·0.5H2O, the water molecule is disordered about an inversion centre. Both phosphorus atoms shows distortions in their tetrahedral environments with the cyclohexyl substituents disordered over two orientations in a 0.851 (3):0.149 (3) occupancy ratio. The crystal structure is assembled via O - H⋯O interactions between pairs of phosphininc amide molecules and water molecules, creating hydrogen-bonded dimers with graph-set R 2 4(8) along [001]. Weak C - H⋯O interactions are also observed.
