Bis[4-(2-nitro-benzene-sulfonamido)-pyridinium] hexa-fluoro-silicate.

ABSTRACT: In the title compound, 2C(11)H(10)N(3)O(4)S(+)·SiF(6) (2-), the short C-N distance [1.386?(2)?Å] is indicative of a slight conjugation of N with the ? electrons of the pyridinium ring, and with those of the sulfonyl group. The dihedral angle between the benzene and pyridinium rings is 77.48?(7)°. The crystal structure is stabilized by N-H?F and C-H?F hydrogen bonds. The Si atom of the anion lies on a special position.

Project description:There are two mol-ecules in the asymmetric unit of the title compound, C(11)H(10)N(3)O(4)S(+)·NO(3) (-). All bond distances have normal values. The C-N bond distances in the sulfonamide group [1.389?(3) and 1.382?(3)?Å] may indicate slight conjugation of the sulfonamide N-atom ?-electrons with those of the pyridinium ring. The crystal structure is stabilized by N-H?O hydrogen bonds.

(±)-Bis(1-carb-oxy-2-phenyl-ethanaminium) hexa-fluoro-silicate(VI).

Project description:The asymmetric unit of the title fluoro-silicate salt, 2C(9)H(12)NO(2) (+)·SiF(6) (2-), consists of a phenylalaninium cation and half of a fluorosilicate anion, the Si atom being located on an inversion center. In the crystal, all of the F atoms act as hydrogen-bond acceptors and link the cations through different graph-set motifs, forming layers developing parallel to (100).

Bis(1,3-dimethyl-1H-imidazolium) hexa-fluoro-silicate methanol 0.33-solvate.

Project description:The title compound, 6C5H9N2 (+)·3SiF6 (2-)·CH3OH, (I), was prepared by recrystallization of the crude salt from methanol along with solvent-free 2C5H9N2 (+)·SiF6 (2-) (II). Crystals of these solvatomorphs can be separated manually. The solvate (I) crystallizes in a rare hexa-gonal space group P6/mcc. Its asymmetric unit comprises one half of an imidazolium cation bis-ected by the crystallographic m-plane, one-sixth and one-twelfth of two crystallographically independent SiF6 (2-) dianions (Si atoms are located on the 3.2 and 6/m inversion centres), and one-twelfth of a methanol mol-ecule (C atoms are situated on the 622 inversion centres, other atoms are disordered between general positions). In (I), all F atoms of 3.2-located SiF6 (2-) dianions participate in the formation of symmetry-equivalent contacts to the H atoms of imidazolium fragments, thus forming rod-type ensembles positioned on the -6 axes. These 'pillar' rods are, in turn, F?H inter-linked through SiF6 (2-) dianions disordered around the 6/m centres. The twelvefold disordered methanol mol-ecules are appended to this array by O-H?F hydrogen bonds to the 6/m located SiF6 (2-) dianions. In terms of graph-set notation, the first and second level networks in (I) are N 1 = C 2 (2)(7)[3R 4 (4)(14)]D 2 (2)(4) and N 2 = D 2 (2)(5) (C-H?O hydrogen bonds are not considered). After locating all symmetrically independent atoms in the cation and anions, there remained a strong (> 3 e Å(-3)) residual electron density peak located at the 622 inversion centre. Treatment of this pre-refined model with the SQUEEZE procedure in PLATON [Spek (2009). Acta Cryst. D65, 148-155] revealed two voids per unit cell, indicative of the presence of the solvent methanol mol-ecule disordered about the 622 inversion centre.
