Crystal structure of benzyl(methyl)phenyl[(piperidin-1-ium-1-yl)methyl]silane bromide
The title compound, C20H29NSi(+)·Br(-), contains a chiral silicon atom but crystallizes as a racemate. The C-Si-C bond angles in the range of 103.64 (8)-111.59 (9)° are usual for tetra-hedral geometry. The piperidine ring shows a regular chair conformation with an equatorially positioned exocyclic N-C bond. In the crystal, there is a hydrogen bond between the ammonium cation and the bromide ani...
متن کاملCrystal structure of 1,3-bis(2,6-diisopropylphenyl)-4,5-dimethyl-1H-imidazol-3-ium bromide dichloromethane disolvate
The title solvated salt, C29H41N2 (+)·Br(-)·2CH2Cl2 was obtained from the reaction of the Arduengo-type carbene 1,3-bis-(2,6-diiso-propyl-phen-yl)-1,3-dihydro-4,5-dimethyl-2H-imidazol-2-ylidene with Si2Br6 in di-chloro-methane. The complete cation is generated by a crystallographic mirror plane and the dihedral angle between the five-membered ring and the benzene ring is 89.8 (6)°; the dihedral...
متن کاملCrystal structure of 3-mesityl-1-[(pyridin-2-yl)methyl]-3,4,5,6-tetrahydropyrimidin-1-ium bromide monohydrate
In the title hydrated salt, C19H24N3 (+)·Br(-)·H2O, the values of the N-C bond lengths within the tetra-hydro-pyrimidinium ring indicate delocalization of the N=C double bond. In the cation, the dihedral angle formed by the pyridine and benzene rings is 14.97 (12)°. In the crystal, ions and water mol-ecules are linked by O-H⋯Br, O-H⋯N, C-H⋯Br and C-H⋯O hydrogen bonds into chains running paralle...
متن کاملCrystal structure of 1,3-bis(4-methylbenzyl)-1H-1,3-benzimidazol-3-ium bromide monohydrate
In the title hydrated symetrically substituted 1,3-bis-(4-methyl-benz-yl)benzimidazolium salt, C23H23N2 (+)·Br(-)·H2O, the dihedral angles between the benzimidazole ring system (r.m.s. deviation = 0.003 Å) and the pendant benzene rings are 73.18 (16) and 77.52 (16)°. Both benzene rings lie to the same side of the benzimidazole ring system, giving the cation an overall U-shape. In the crystal, t...
متن کاملCrystal structure of morpholin-4-ium cinnamate
In the anhydrous salt formed from the reaction of morpholine with cinnamic acid, C4H10NO(+)·C9H7O2 (-), the acid side chain in the trans-cinnamate anion is significantly rotated out of the benzene plane [C-C-C- C torsion angle = 158.54 (17)°]. In the crystal, one of the the aminium H atoms is involved in an asymmetric three-centre cation-anion N-H⋯(O,O') R 1 (2)(4) hydrogen-bonding inter-action...
