摘要

The title compound, C18H18NOP, was obtained during a search for new P,N-containing ligands with the potential to generate precatalysts with chromium(III) for selective ethyl­ene oligomerization. In the crystal, mutual pairs of N—H⋯O=P hydrogen bonds link two mol­ecules into a dimer with individual mol­ecules related by a twofold rotation axis. The P=O bond length of 1.4740 (15) Å is not elongated although the O atom is involved in hydrogen bonding. The crystal structure is further stabilized by van der Waals inter­actions between the dimers, linking the mol­ecules into a three-dimensional network structure.
