N-[3-(Dimethylamino)propyl]-N,N',N',N'',N''-pentamethylguanidinium tetraphenylborate

I. Tiritiris

Abstract top

In the title salt, C11H27N4+·C24H20B-, the C-N bond lengths in the central CN3 unit of the guanidinium ion are 1.333 (4), 1.334 (4) and 1.351 (4) Å, indicating partial double-bond character. The C atom of this unit is bonded to the three N atoms in a nearly ideal trigonal-planar geometry [N-C-N angles = 118.8 (3), 120.0 (3) and 121.2 (3)°] and the positive charge is delocalized in the CN3 plane. The bonds between the N atoms and the terminal C-methyl groups of the guanidinium moiety have values in the range 1.459 (4)-1.478 (4) Å, close to a typical single bond. In the crystal, there are C-H...[pi] interactions between the guanidinium H atoms and the phenyl rings of the tetraphenylborate ion. These interactions combine to form a ladder of linked chains of ions which runs parallel to the c axis.

Comment top

ω-Aminoalkylguanidines like N''-[3-(dimethylamino)propyl]- N,N,N',N'-tetramethylguanidine (I) (Tiritiris & Kantlehner, 2012), in which two nitrogen atoms with different basicity are present, are considered as ambident nucleophiles. Electrophiles can attack at both, on the imine nitrogen of the guanidine function, as well as on the nitrogen atom of the (dimethylamino)propyl group. By alkylation of (I) with only one equivalent dimethyl sulfate, methylation occurs preferentially at the guanidine nitrogen atom, because it is the most basic site. The exclusion of moisture and the use of absolutely acid free dimethyl sulfate, is in this reaction very essential. Otherwise in first step protonation of the guanidine nitrogen atom occurs, followed by methylation of the (dimethylamino)propyl group, resulting in the dicationic N,N,N',N'-tetramethyl-N''-[3- (trimethylazaniumyl)propyl]guanidinium ion (Tiritiris, 2013) as the main product. In fact, the reaction in wet solvents and the presence of acid traces, yields salt mixtures consisting of monocationic and dicationic species, which cannot be easily separated from each other. When performing the reaction under anhydrous conditions, the obtained waxy monomethylated methyl sulfate salt was converted after subsequent anion exchange with sodium tetraphenylborate to the crystalline title compound, whose X-ray structure is presented here.

According to the structure analysis, the C1–N1 bond of the the CN3 unit is 1.351 (4) Å, C1–N2 = 1.334 (4) Å and C1–N3 = 1.333 (4) Å, showing partial double-bond character. The N–C1–N angles are: 118.8 (3)° (N1–C1–N2), 120.0 (3)° (N1–C1–N3) and 121.2 (3)° (N2–C1–N3), which indicates a nearly ideal trigonal-planar surrounding of the carbon centre by the nitrogen atoms. The positive charge is completely delocalized on the CN3 plane (Fig. 1). The bonds between the N atoms and the terminal C-methyl groups of the guanidinium moiety all have values in the range 1.459 (4)–1.478 (4) Å, close to a typical single bond. The C–N bond lengths in the (dimethylamino)propyl group range from 1.437 (6) to 1.489 (6)Å. The bond lengths and angles in the tetraphenylborate ions are in good agreement with the data from the crystal structure analysis of the alkali metal tetraphenylborates (Behrens et al., 2012). C–H···π interactions between the guanidinium hydrogen atoms of –N(CH3)2 and –CH2 groups and the phenyl carbon atoms (centroids) of the tetraphenylborate ion are present (Fig. 2), ranging from 2.48 to 2.89 Å (Tab. 1). These interactions combine to form a ladder of linked chains of ions which runs parallel to the c axis.

Experimental top

The title compound was obtained by reaction of N''-[3-(dimethylamino)propyl]-N,N,N',N'-tetramethylguanidine (Tiritiris & Kantlehner, 2012) with one equivalent of freshly distilled dimethyl sulfate in anhydrous acetonitrile at room temperature. After evaporation of the solvent the crude N,N,N',N',N''-pentamethyl-N''-[3-(dimethylamino)propyl]-guanidinium methyl sulfate (II) was washed with diethylether and dried in vacuo. 1.0 g (2.8 mmol) of (II) was dissolved in 20 ml acetonitrile and 0.96 g (2.8 mmol) of sodium tetraphenylborate in 20 ml acetonitrile were added. After stirring for one hour at room temperature, the precipitated sodium methyl sulfate was filtered off. The title compound crystallized from a saturated acetone solution after several weeks at 273 K, forming colorless single crystals. Yield: 1.15 g (76.8%).

Refinement top

The title compound crystallizes in the non-centrosymmetric space group Pna21; however, in the absence of significant anomalous scattering effects, the Flack parameter is essentially meaningless. Accordingly, Friedel pairs were merged. The hydrogen atoms of the methyl groups were allowed to rotate with a fixed angle around the C–N bond to best fit the experimental electron density, with Uiso(H) set to 1.5 Ueq(C) and d(C—H) = 0.98 Å. The remaining H atoms were placed in calculated positions with d(C—H) = 0.99 Å (H atoms in CH2 groups) and (C—H) = 0.95 Å (H atoms in aromatic rings). They were included in the refinement in the riding model approximation, with Uiso(H) set to 1.2 Ueq(C).

Special details top

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.
