(Received 21 October 2008; accepted 23 October 2008; online 31 October 2008)

In the mol­ecule of the title compound, C20H17NP+·Cl−, the coordination around the P atom is slightly distorted tetra­hedral. In the crystal structure, inter­molecular C—H⋯N and C—H⋯Cl hydrogen bonds link the mol­ecules. There is a π–π contact between the phenyl rings [centroid–centroid distance = 3.702 (3) Å].

Comment top

Triphenyl phosphonium compounds are key reagents in the Wittig reactions, used to convert aldehydes and ketones into alkenes. The Wittig reaction has seen use in applications ranging from the synthesis of simple alkenes to the construction of complex biologically active molecules for the pharmaceutical industry.The title compound is synthesized for the derivatization of our already published structures (Shafiq et al., 2008; Tahir et al., 2008) using this particular reaction. Various structures have been published having the similar geometry around P atom (Skapski & Stephens, 1974; de Dubourg et al., 1986; Czerwinski & Ponnuswamy, 1988; Fischer & Wiebelhaus, 1997; Czerwinski, 2004).

In the molecule of the title compound (Fig 1), the geometry around P atom is slightly distorted tetrahedral (Table 1). Rings A (C1-C6), B (C7-C12) and C (C13-C18) are of course planar. The dihedral angles between them are A/B = 86.10 (11)°, A/C = 89.78 (10)° and B/C = 76.23 (12)°.

In the crystal structure, intramolecular C-H···Cl and intermolecular C-H···N and C-H···Cl hydrogen bonds (Table 2) link the molecules (Fig. 2), in which they may be effective in the stabilization of the structure. The π—π contact between the phenyl rings, Cg3···Cg3i [symmetry code: (i) 2 - x, -y, 1 - z, where Cg3 is the centroid of the ring C (C13-C18)] may further stabilize the structure, with centroid-centroid distance of 3.702 (3) Å. There also exist a C—H···π contact (Table 2) between the phenyl rings.

Experimental top

Triphenylphosphine (10 g, 0.038 mol) was dissolved in benzene (20 ml) under stirring at room temperature. To this solution, chloroacetonitrile (4 g, 0.0514 mole) was added dropwise. After complete addition, clear solution formed was left in the darkness for 2-3 d. Colorless crystals formed were separated for X-ray diffraction studies.

Refinement top

H-atoms were positioned geometrically, with C-H = 0.93 and 0.97 Å for aromatic and methylene H, and constrained to ride on their parent atoms, with Uiso(H) = 1.2Ueq(C).

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
