In the title salt, C15H36N62+·2C24H20B−, the three N—C bond lengths in the central C3N unit of the bisamidinium ion range between 1.388 (3) and 1.506 (3) Å, indicating single- and double-bond character. Furthermore, four C—N bonds have double-bond character. Here, the bond lengths range from 1.319 (3) to 1.333 (3) Å. Delocalization of the positive charges occurs in the N/C/N and C/N/C planes. The dihedral angle between both N/C/N planes is 70.5 (2)°. In the crystal, C—H⋯π interactions between H atoms of the cation and the benzene rings of both tetraphenylborate ions are present. The benzene rings form aromatic pockets, in which the bisamidinium ion is embedded. This leads to the formation of a two-dimensional supramolecular pattern along the ab plane.

The title compound has been obtained by reaction of N''-[3-(dimethylamino)propyl]-N,N,N',N'-tetramethylguanidine (I) (Tiritiris & Kantlehner, 2012b) with one equivalent of N,N,N',N'- tetramethylchloroformamidinium chloride (Tiritiris & Kantlehner, 2008) in acetonitrile at room temperature. After evaporation of the solvent the crude N-[3-(dimethylamino)propyl]-N-(N,N,N',N'-tetramethyl-formamidinio)-N',N',N'',N''-tetramethyl-guanidinium dichloride (II) was washed with diethylether and dried in vacuo. 1.0 g (2.7 mmol) of (II) was dissolved in 20 ml acetonitrile and 1.83 g (5.4 mmol) of sodium tetraphenylborate in 20 ml acetonitrile were added. After stirring for one hour at room temperature, the precipitated sodium chloride was filtered off. The title compound crystallized from a saturated acetonitrile solution after a few months at 273 K, forming colorless single crystals. Yield: 2.15 g (84.9%).
A total number of 34135 reflections have been measured. The data where scaled in the chiral
C2 per default by using SCALEPACK (Otwinowski & Minor, 1997). After merging all symmetry related reflections and Friedel pairs, a total number of 6569 unique reflections remained (Theta range: 0.41°-28.28°; data completeness: 97.7%; Rint= 0.044). Therefore Rint given by SHELXL2014/7 (Sheldrick, 2015) is meaningless. The data in the hkl file used for structure solution and were also scaled in the chiral C2, but here the Friedel pairs were kept separate. The title compound crystallizes in the non-centrosymmetric Cc; however, in the absence of significant effects, the determined x = -0.8 (8) (Parsons et al., 2013) is essentially meaningless. 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 1.5Ueq(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) and refined using a riding model, with Uiso(H) set to 1.2 Ueq(C).ω-Aminoalkylguanidines like N''-[3-(dimethylamino)propyl]- N,N,N',N'-tetramethylguanidine (I) (Tiritiris & Kantlehner, 2012b), 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 reaction of (I) with one equivalent N,N,N',N'- tetramethylchloroformamidinium chloride (Tiritiris & Kantlehner, 2008), the hygroscopic bisamidinium dichloride (II) was formed exclusively. As expected, the reaction occurred preferably at the imine nitrogen of the guanidine function because it is the most basic site. Two similar bisamidinium dichlorides are known in the literature. They where obtained by reaction of N,N,N',N'- tetramethylchloroformamidinium chloride (Tiritiris & Kantlehner, 2008) with N,N,N',N',N''-pentamethylguanidine or N-phenyl-N',N',N'',N''-tetramethylguanidine, respectively (Bauer et al., 1968). In our case, by with sodium tetraphenylborate it was possible to obtain a stable, non-hygroscopic salt. The here presented is the first structural study of a dicationic nonasubstituted bisamidinium salt. The contains one twofold charged cation and two tetraphenylborate ions (Fig. 1). Prominent bond parameters in the bisamidinium ion are: N5–C6 = 1.388 (3) Å, N5–C1 = 1.407 (3) Å, N5–C11 = 1.506 (3) Å, indicating N–C single- and double-bond character of the central C3N unit. The C–N–C angles are 117.51 (17)°, 118.92 (17)° and 123.16 (17)°, indicating a nearly ideal trigonal-planar surrounding of the central nitrogen atom N5 by the carbon atoms C1, C6 and C11. The carbon atoms C1 and C6 are further surrounded by the nitrogen atoms N1, N2, N3 and N4. Here, the C–N bonds show double-bond character and the bond lengths range from 1.319 (3) Å to 1.333 (3) Å. The N–C–N angles range from 118.24 (19)° to 121.87 (19)°, indicating again nearly ideal trigonal-planar surroundings of both carbon centres by the nitrogen atoms. The positive charges are delocalized in the planes N1/C1/N2, N3/C6/N4 and C1/N5/C6. The dihedral angle between the plane N1/C1/N2 and N3/C6/N4 is 70.5 (2)°. The bond lengths and angles in both tetraphenylborate ions are in good agreement with the data from the analysis of the alkali metal tetraphenylborates (Behrens et al., 2012a). C–H···π interactions between the bisamidinium hydrogen atoms of –N(CH3)2 and –CH2 groups and the phenyl carbon atoms [centroids: Cg1 = C22–C27, Cg2 = C28–C33 and Cg3 = C58–C63] of the tetraphenylborate ion are present (Fig. 2), ranging from 2.63 to 2.97 Å (Tab. 1). Such type of C–H···π interactions have been observed in tetraphenylborate salts with pentasubstituted or hexasubstituted guanidinium ions [for example: N,N,N',N'- tetramethyl-N''-[3-(trimethylazaniumyl)propyl]guanidinium bis(tetraphenylborate) acetone disolvate (Tiritiris, 2013a); N-[3-(Dimethylamino)propyl]- N,N',N',N'',N''- pentamethylguanidinium tetraphenylborate (Tiritiris, 2013b)]. The phenyl rings form aromatic pockets, in which the cation is embedded. This leads finally to the formation of a two-dimensional supramolecular pattern along the ab plane.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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. |

ω-Aminoalkylguanidines like N''-[3-(dimethylamino)propyl]- N,N,N',N'-tetramethylguanidine (I) (Tiritiris & Kantlehner, 2012b), 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 reaction of (I) with one equivalent N,N,N',N'- tetramethylchloroformamidinium chloride (Tiritiris & Kantlehner, 2008), the hygroscopic bisamidinium dichloride (II) was formed exclusively. As expected, the reaction occurred preferably at the imine nitrogen of the guanidine function because it is the most basic site. Two similar bisamidinium dichlorides are known in the literature. They where obtained by reaction of N,N,N',N'- tetramethylchloroformamidinium chloride (Tiritiris & Kantlehner, 2008) with N,N,N',N',N''-pentamethylguanidine or N-phenyl-N',N',N'',N''-tetramethylguanidine, respectively (Bauer et al., 1968). In our case, by anion exchange with sodium tetraphenylborate it was possible to obtain a stable, non-hygroscopic salt. The here presented crystal structure is the first structural study of a dicationic nonasubstituted bisamidinium salt. The asymmetric unit contains one twofold charged cation and two tetraphenylborate ions (Fig. 1). Prominent bond parameters in the bisamidinium ion are: N5–C6 = 1.388 (3) Å, N5–C1 = 1.407 (3) Å, N5–C11 = 1.506 (3) Å, indicating N–C single- and double-bond character of the central C3N unit. The C–N–C angles are 117.51 (17)°, 118.92 (17)° and 123.16 (17)°, indicating a nearly ideal trigonal-planar surrounding of the central nitrogen atom N5 by the carbon atoms C1, C6 and C11. The carbon atoms C1 and C6 are further surrounded by the nitrogen atoms N1, N2, N3 and N4. Here, the C–N bonds show double-bond character and the bond lengths range from 1.319 (3) Å to 1.333 (3) Å. The N–C–N angles range from 118.24 (19)° to 121.87 (19)°, indicating again nearly ideal trigonal-planar surroundings of both carbon centres by the nitrogen atoms. The positive charges are delocalized in the planes N1/C1/N2, N3/C6/N4 and C1/N5/C6. The dihedral angle between the plane N1/C1/N2 and N3/C6/N4 is 70.5 (2)°. The bond lengths and angles in both tetraphenylborate ions are in good agreement with the data from the crystal structure analysis of the alkali metal tetraphenylborates (Behrens et al., 2012a). C–H···π interactions between the bisamidinium hydrogen atoms of –N(CH3)2 and –CH2 groups and the phenyl carbon atoms [centroids: Cg1 = C22–C27, Cg2 = C28–C33 and Cg3 = C58–C63] of the tetraphenylborate ion are present (Fig. 2), ranging from 2.63 to 2.97 Å (Tab. 1). Such type of C–H···π interactions have been observed in tetraphenylborate salts with pentasubstituted or hexasubstituted guanidinium ions [for example: N,N,N',N'- tetramethyl-N''-[3-(trimethylazaniumyl)propyl]guanidinium bis(tetraphenylborate) acetone disolvate (Tiritiris, 2013a); N-[3-(Dimethylamino)propyl]- N,N',N',N'',N''- pentamethylguanidinium tetraphenylborate (Tiritiris, 2013b)]. The phenyl rings form aromatic pockets, in which the cation is embedded. This leads finally to the formation of a two-dimensional supramolecular pattern along the ab plane.
