The title 3P)2N]Cl·(B(OH)3) or C36H30NP2+·Cl−·BH3O3. The of the orthorhombic polymorph was reported by [Andrews et al. (1983). Acta Cryst. C39, 880–882]. In the crystal, the [(Ph3P)2N]+ cations have no significant contacts to the chloride ions nor to the boric acid molecules. This is indicated by the P—N—P angle of 137.28 (8)°, which is in the expected range for a free [(Ph3P)2N]+ cation. The boric acid molecules form inversion dimers via pairs of O—H⋯O hydrogen bonds, and each boric acid molecule forms two additional O—H⋯Cl hydrogen bonds to one chloride anion. These entities fill channels, created by the [(Ph3P)2N]+ cations, along the c-axis direction.

Single crystals of the title compound, suitable for X-ray diffraction, were obtained as an hydrolysis product of [(Ph3P)2N][BCl4] by layering an acetonitrile solution with diethyl ether.
All hydrogen atoms attached to the aromatic rings were placed in calculated positions (C—H = 0.93 Å) and refined as riding atoms, with Uiso(H) = 1.2 Ueq(C). The oxygen-bonded H atoms were located in a difference Fourier map and freely refined.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
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 > 2σ(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. All hydrogen atoms attached to the aromatic rings were placed in calculated positions (C—H = 0.93 Å) and refined as riding atoms, with Uiso(H) = 1.2 Ueq(C). The oxygen-bonded hydrogen atoms were taken from the Fourier map and were refined isotropically. |

Often the [(Ph3P)2N]+ cation is partnered by a bulky anion, while crystal structures containing small anions and especially halides are rare. Only very recently, the crystal structures of the solvate-free halides [(Ph3P)2N]I (Beckett et al., 2010) and [(Ph3P)2N]Cl (Knapp & Uzun, 2010a) and the acetonitrile solvate [(Ph3P)2N]Br.CH3CN (Knapp & Uzun, 2010b) and the dichloride [(Ph3P)2N][ClHCl] (Gellhaar & Knapp, 2011) were published.
In the course of our investigations on the crystal structures of [(Ph3P)2N]+ salts with small counter anions, colourless single crystals of [(Ph3P)2N]Cl.(B(OH)3) were isolated from an acetonitrile/diethyl ether solution. This compound is formed by hydrolysis of [(Ph3P)2N][BCl4]. The dichloride [(Ph3P)2N][ClHCl] (Gellhaar & Knapp, 2011) was identified as a by-product of this hydrolysis reaction by single-crystal X-ray diffraction.
Surprisingly, the determined crystal structure of [(Ph3P)2N]Cl.(B(OH)3), Fig. 1, is distinctly different from the crystal structure (orthorhombic, Pbca, a = 19.010 (3), b= 18.869 (4), c= 18.432 (6) Å), which was reported previously for this compound (Andrews et al., 1983) and thus represents a second polymorph. It can be assumed that different crystallization conditions, dichloromethane/n-hexane (Andrews et al., 1983) versus acetonitrile/diethyl ether (this work), caused the crystallization of different polymorphs. The two polymorphs show different orientations of the phenyl groups of the [(Ph3P)2N]+ cation and a different orientation of the anionic and cationic parts relative to each other in the crystal lattice. The herein reported polymorph has a higher density (1.315 Mg m-3, T =150 K) than the structure reported by Andrews et al. (1.277 Mg m-3, T=291 k).
The bis(triphenyl-λ5-phosphanylidene)ammonium cation shows bond angles (P—N—P angle [137.28 (8)°]) and bond lengths (P—N (1.5836 (12) and 1.5839 (12) Å) and P—C distances (1.7951 (15)–1.8004 (16) Å) in the expected range (Lewis & Dance, 2000).
In the crystal, the boric acid molecules form inversion dimers via a pair of O—H···O hydrogen bonds (Fig. 2 and Table 1). Each boric acid molecule forms two additional O—H···Cl hydrogen bonds to one chloride ion (Fig. 2 and Table 1). This part of the crystal structure is very similar to the boric acid dimer in the orthorhombic polymorph.
