dc.description.abstract	<span>The title compound, C<sub>26</sub>H<sub>38</sub>ClN<sub>2</sub>OP, was synthesized by reacting phosphoryl chloride with <em>N</em>,<em>N</em><sup>′</sup>-bis(2,6-diisopropylphenyl)ethane-1,2-diamine in the presence of <em>N</em>-methylmorpholine which acted as an auxilliary base to quench the HCl released as a by-product. The resultant <em>N</em>-heterocyclic phosphine five-membered ring adopts a half-chair conformation and features a tetracoordinate P atom ligated by the chelating diamine [P—N = 1.6348 (14) and 1.6192 (14) Å], one double-bonded O atom [P1—O1 = 1.4652 (12) Å] and one Cl atom [P1—Cl1 = 2.0592 (7) Å]. The sterically hindered 2,6-diisopropylphenyl (Dipp) groups twist away from the central heterocycle, with torsion angles of −75.66 (19) and 83.39 (19)° for the P—N—C<sub>ar</sub>—C<sub>ar</sub> links. A number of intramolecular C—H<sup>...</sup>N, C—H<sup>...</sup>O and C—H<sup>...</sup>Cl close contacts occur. In the crystal, molecules are linked by C—H<sup>...</sup>O hydrogen bonds to generate [010] chains. C—H<sup>...</sup></span><sub><sup>Π </sup></sub>interactions are also observed.	en_CA
