Abstract

The title compound, C(18)H(15)OP·C(13)H(17)N(2)O(3), belongs to a series of mol-ecular systems based on triphenyl-phosphine oxide. The O atom of the oxide group acts as an acceptor for hydrogen bonds from -OH groups of the nitronyl nitroxide. The crystal structure is stabilized by O-H⋯O hydrogen bonds.
