title: 2-[Bis(3,5-dimethyl-phen-yl)-phosphor-yl]-propan-2-ol hemihydrate.
abstract: In the organic mol-ecule of the title compound, C(19)H(25)O(2)P·0.5H(2)O, the benzene rings are oriented at a dihedral angle of 54.04 (3)°. Intra-molecular C-H⋯O hydrogen bonds result in the formation of two five-membered planar rings, which are oriented with respect to the adjacent benzene rings at dihedral angles of 2.66 (3) and 2.79 (3)°. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules. The water oxygen atom lies on a twofold rotation axis.
