The title compound, C11H20N2PS+·BF4−, is a salt of 2-(diisopropylthiophosphorylamino)pyridine, a chelating bidentate ligand that furnishes an S atom as a soft donor and a pyridine N atom as a hard atom for transition-metal complexation. The title salt crystallizes with two formula units in the The two independent cations are protonated at the pyridine N atoms and have the S atoms syn-oriented to them so as to form bent intramolecular N—H⋯S hydrogen bonds, one of which one is bifurcated by involving also an N—H⋯F interaction. The phosphorylamino NH groups form near linear hydrogen bonds to proximal tetrafluoroborate anions. Five weak C—H⋯F and three weak C—H⋯S interactions link the constituents into a three-dimensional framework. As a result of the crystal packing, the two cations differ notably in conformation, as can be seen from the S—P—N—C torsion angles of −18.7 (1)° in the first and −35.1 (1)° in the second cation.

2-(Diisopropylthiophosphorylamino)-pyridine (Öztopcu et al., 2011; Smith & Sisler, 1961; 1.03 mmol, 250 mg) was dissolved in dry CH2Cl2 and 1.05 equivalent of HBF4 in Et2O was added. The solvent was removed under reduced pressure and the solid residue was washed twice with 15 ml dry Et2O. Yield: 326 mg, 95.7%, white solid. Colourless crystals of the title compound for X-ray diffraction were obtained from a CH2Cl2 solution by vapour diffusion of Et2O. 1H NMR (δ, CD2Cl2, 20°C): 15.15 (bs, 1H, [pyH]+), 8.12 (t, J = 7.8 Hz, 1H, py6),7.98 – 7.90 (m, 2H, py4, NH), 7.84 (d, J = 9.0 Hz, 1H, py3),7.25 (t, 6.8 Hz, 1H, py5), 2.65 – 2.51 (m, 2H, CH(CH3)2), 1.38 – 1.23 (m, 12H, CH(CH3)2). 13C{1H}NMR (δ, CH2Cl2, 20°C): 154.6 (s, py2), 146.0(s, py6), 135.0 (s, py4), 118.2 (s, py5), 117.2 (s, py3), 31.1 (d, J = 57.2 Hz, CH(CH3)2), 15.4 (s, CH(CH3)2), 15.1 (s, CH(CH3)2). 31P{1H}NMR (δ, CD2Cl2, 20°C): 107.2.
C-bonded H atoms were placed in calculated positions and thereafter treated as riding, C—H = 0.95–1.00 Å, Uiso(H) = 1.2Ueq(C). N-bonded H atoms were fully 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 > 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. |

Dialkyl- and diaryl-thiophosphoryl derivatives of 2-aminopyridine are chelating bidentate ligands, which furnish a pyridine nitrogen as a hard and a sulfur as a soft donor site for transition metal coordination. This dual property is desirable for reactive transition metal complexes (Bayón et al., 1999) and, accordingly, a variety of such complexes have been studied in recent years (Öztopcu et al., 2011; Bichler et al., 2011). During recent work in this field (Holzhacker et al., 2011), the title compound was obtained in suitable crystals and was studied by X-ray diffraction. It crystallizes in the triclinic space group P1 and contains two formula units [C11H20N2PS]+(BF4)- in the asymmetric unit (Fig. 1). In (I), both organocations [SN-iPr]H+ possess very similar bond lengths and bond angles, but differ significantly in their conformation, as can be seen from the torsion angles S1—P1—N2—C1 = -18.72 (10)° and P1—N2—C1—N1 = -16.91 (14)° in the first cation and corresponding values of -35.14 (10)° and +6.74 (14)° in the second cation. The conformation of the [SN-iPr]H+ moiety in (I) is related to that of its metal chelate complexes (Öztopcu et al., 2011; Bichler et al., 2011; Holzhacker et al., 2011), which have the S atoms like in (I) syn-oriented to the pyridine N, but different from the solid state structure of the unprotonated neutral parent molecule [SN-iPr], in which the S atom points away from the pyridine nitrogen corresponding to a S1—P1—N2—C1 torsion angle near 180° (Öztopcu et al., 2011). Compared with the neutral parent molecule [SN-iPr], the bond lengths and bond angles in (I) are modestly altered by the pyridine N-protonation with subtle changes of about 0.01 - 0.02 Å in the P1—N2—C1—N1—C5 / P2—N4—C12—N3—C16 system and a significant increase of the ring bond angles C1—N1—C5 / C12—N3—C16 from ca 117° in [SN-iPr] (Öztopcu et al., 2011) to ca 123° in [SN-iPr]H+ of (I). Both pyridinium moieties in (I) donate strongly bent intramolecular hydrogen bonds to the sulfur atoms as acceptors with N···S distances of 3.136 (1) Å and 3.130 (1) Å for cation 1and 2, respectively (Table 1). For cation 1, the N1—H1n group has in addition to S1 also a fluorine F2(1 + x,y,z) nearby and the entire interaction has to be classified as an asymmetrically branched bifurcated hydrogen bond (N1—H1n···S1,F2; the sum of the three bond angles about H1n is 358°). The phosphorylamine NH groups, which are distinctly acidic irrespective whether the pyridine fragment is protonated or not, form comparatively straight N—H···F hydrogen bonds to the BF4 anions with N···F distances of 2.807 (1) and 2.871 (1) Å (Table 1). In the parent compound [SN-iPr] the phosphorylamine NH groups donate intermolecular N—H···S hydrogen bonds of N···S = 3.38 and 3.47 Å to neighbouring molecules (Öztopcu et al., 2011). A partial packing diagram showing the N—H donated hydrogen bonds in (I) is presented in Fig. 2. Three-dimensional coherence of the structure is provided by five different C—H···F and three C—H···S interactions listed in Table 1.
