Abstract:
The mol-ecular structure of the title compound, C(22)H(34)N(3)OP, adopts a distorted tetra-hedral geometry at the P atom, with the most noticeable distortion being for the O-P-N angle [117.53 (10)°]. An effective cone angle of 187° was calculated for the compound. In the crystal, weak C-H⋯O inter-actions create infinite chains along [100], whereas C-H⋯π inter-actions propagating in [001] generate a herringbone motif.
