Comment
=======

This structure forms part of ongoing research on ethylene tetramerization. In the title compound, all bond distances and angles are normal and fall within the range for similar complexes (Keat *et al.*, 1981; Cotton *et al.*, 1996; Cloete *et al.*, 2008; 2009; 2010). The distance of N1 from the P1---P2---C1 plane is 0.098 (2) Å showing that the N atom adapts a planar geometry with these atoms in order to accomodate the steric bulk of the phenyl groups. Dihedral angles were calculated based on planes defined by each phenyl ring and the neighboring P atom. The dihedral angles between the various phenyl rings within the molecule are: C1/C2 = 51.74 (5) ° and C3/C4 = 68.23 (4) °. TThe distorted tetrahedral angles of the P atoms range between 100.43 (7) and 105.26 (7) ° which is in good comparison with those in literature. There are no classical intermolecular hydrogen interactions. The title compound is a C~s~ conformer in the solid state (Keat *et al.*, 1981) in which the phosphorous lone pairs are *trans* with respect to the N--C bond.

Experimental {#experimental}
============

Cyclopropylamine (0.010 mol, 693 µl) was dissolved in dichloromethane (30 ml) after which the solution was placed on an ice bath. Triethylamine (0.030 mol, 4.21 ml) was added to the solution while stirring. Chlorodiphenylphosphine (0.020 mol, 3.70 ml) was slowly added to the reaction mixture. The ice bath was removed after 1 h and the reaction mixture was allowed to stir at room temperature for a further 13 h. The dichloromethane was removed under reduced pressure. A mixture of hexane (20 ml) and toluene (2 ml) was added to the remaining white powder and was passed through a column containing neutral activated alumina (35 g). The solvent of the eluent was removed under reduced pressure and the white precipitate was collected. Single colourless crystals suitable for X-ray crystallography were obtained from recrystallization from methanol. (yield: 1.807 g, 43%)

Refinement {#refinement}
==========

The methine, methylene and aromatic H atoms were placed in geometrically idealized positions at C---H = 1.00, 0.99 and 0.95 Å, respectively and constrained to ride on their parent atoms, with *U*~iso~(H) = 1.2*U*~eq~(C). The highest peak is located 0.71 Å from C43 and the deepest hole is situated 0.53 Å from P1.

Special details {#specialdetails}

  ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
  Experimental. The intensity data were collected on a Bruker X8 ApexII 4 K Kappa CCD diffractometer using an exposure time of 10 s/frame. A total of 1407 frames were collected with a frame width of 0.5° covering up to θ = 28.36° with 99.3% completeness accomplished. Spectroscopy data: ^1^H NMR (300 MHz, CD~2~Cl~2~): δ = 0.3 to 0.7 (m, 4H, 2 *x* CH~2~), 2.6 (m, 1H, CH), 7.3 to 7.5 (m, 20H, Ar); ^31^P NMR (121 MHz, CD~2~Cl~2~): δ = 63.4 (*s*).
  Geometry. All s.u.\'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.\'s are taken into account individually in the estimation of s.u.\'s in distances, angles and torsion angles; correlations between s.u.\'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.\'s is used for estimating s.u.\'s involving l.s. planes.
  Refinement. Refinement of *F*^2^ against ALL reflections. The weighted *R*-factor *wR* and goodness of fit *S* are based on *F*^2^, conventional *R*-factors *R* are based on *F*, with *F* set to zero for negative *F*^2^. The threshold expression of *F*^2^ \> 2σ(*F*^2^) is used only for calculating *R*-factors(gt) *etc*. and is not relevant to the choice of reflections for refinement. *R*-factors based on *F*^2^ are statistically about twice as large as those based on *F*, and *R*- factors based on ALL data will be even larger.
