Source of material

Triphenylphosphane (Sigma; 0.26 g, 1 mmol) and 4-methylbenzyl chloride (Sigma; 0.14 g, 1 mmol) were dissolved in ethanol (50 mL) and refluxed for 1 h. The mixture was filtered and colourless crystals of the phosphonium salt were isolated upon cooling to room temperature. Yield: 0.35 g (79.7%). M.pt (Stuart SMP30 digital melting point apparatus; uncorrected): 521–523 K. IR (Bruker Vertex 70v FTIR Spectrometer; cm−1): 1435 (m) ν(C=C), 745 (m) ν(P–C). 1 H NMR (Bruker Ascend 400 MHz NMR spectrometer; CDCl3; ppm relative to Me4Si): 2.20 (s, 3H, CH3), 2.32 (s, 2H, CH2), 6.92–6.98 (m, 2H, Ph–H), 7.60–7.79 (m, 17H, Ph–H). 13 C{ 1 H} NMR (as for 1H NMR): 21.1 (CH3), 30.6 (CH2), 117.7, 118.6, 128.7, 129.5, 130.1, 133.8, 134.4, 134.8 (Ph–C).

Experimental details

The C-bound H atoms were geometrically placed (C–H = 0.95–0.99 Å) and refined as riding with U iso(H) = 1.2–1.5U eq(C). The O-bound atoms were located from a Fourier difference map and refined with O–H = 0.84 +/−0.01 Å, and with U iso(H) = 1.5U eq(O).

Comment

The title salt dihydrate [(4-MeC6H4CH2)Ph3P]Cl.2H2O, hereafter (I), was isolated as a side-product during the attempted synthesis of Ph2(4-MeC6H4CH2)P=O. The synthesis of the triorganophosphane oxide was motivated by on-going structural studies characterising R3P=O adducts of various organotin halides [5, 6].

The molecular structures of the 4-methylbenzyl(triphenyl)phosphonium cation, the chloride anion and two molecules of water of crystallisation comprising the asymmetric unit of (I) are shown in the figure (50% displacement ellipsoids). The P–C bond lengths lie in a narrow range, i.e. from 1.7924(17) Å [P1–C21] to 1.8065(17) [P1–C1]. Similarly, the tetrahedral angles lie in a narrow range, i.e. from 107.53(8)° [C15–P1–C21] to 112.18(8)° [C1–P1–C9]. No specific trends in the geometric parameters are correlated with the methylene-C1 atom. Finally, the sequence of C(x)–P1–C1–C2 torsion angles is 60.99(14), −178.98(12) and −61.83(14)° for x = 9, 15 and 21, respectively, and indicate +syn-clinal, −anti-periplanar and +syn-clinal conformations, respectively.

There are four crystal structures available in the literature featuring the 4-methylbenzyltriphenylphosphonium cation giving a total of six independent cations [710]. The +syn-clinal, −anti-periplanar and +syn-clinal conformations noted for (I) match those in the literature precedents.

Significant conventional hydrogen bonding interactions are apparent in the crystal of (I). The O1w- and O2w-water molecules form similar donor interactions, namely to the chloride and to the other water molecule [O1w–H1w⃛Cl1: H1w⃛Cl1 = 2.40(3) Å, O1w⃛Cl1 = 3.236(2) Å with angle at H1w = 164(3)°; O1w–H2w⃛O2w i : H2w⃛O2w i  = 2.29(3) Å, O1w⃛O2w i  = 2.990(3) Å with angle at H2w = 139(3)°; O2w–H3w⃛O1w: H3w⃛O1w = 2.11(2) Å, O2w⃛O1w = 2.898(3) Å with angle at H3w = 155(3)°; and O2w–H4w⃛Cl1 ii : H4w⃛Cl1 ii  = 2.51(3) Å, O2w⃛Cl1 ii  = 3.3031(19) Å with angle at H4w = 158(2)° for symmetry operations (i) x, 3/2−y, −1/2+z and (ii) x, 3/2−y, 1/2+z]. The hydrogen bonds occur within chains comprising chloride and water molecules along the c-axis; the chain has a zig-zag topology, being propagated by glide symmetry. Connections between the chains and cations within the three-dimensional architecture are of the type methylene-C–H⃛Cl, phenyl-C–H⃛Cl and phenyl-C–H⃛O (water) which are all weak.
