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 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...

In the cation of the title salt, C8H11N2 (+)·Br(-), the dihedral angle between the planes of the pyridinium ring and the allyl group is 79.4 (3)°. In the crystal, N-H⋯Br and weak C-H⋯Br hydrogen bonds link the cations and anions, forming chains of alternating R 2 (1)(7) and R 4 (2)(8) rings, which run parallel to the c-axis direction. The crystal studied was an inversion twin with components in...
متن کاملCrystal structure of 1-hydroxy-2,2,6,6-tetramethylpiperidin-1-ium trifluoromethanesulfonate
In the cation of the title salt, C9H20NO(+)·CF3O3S(-), the six-membered heterocyclic ring displays a chair conformation. In the crystal, centrosymmetric pairs of cations and anions are linked by N-H⋯O and O-H⋯O hydrogen bonds to form rings with a R 4 (4)(14) graph-set motif.
متن کاملCrystal structure of 4-hydroxypyridin-1-ium 3,5-dicarboxybenzoate
The structure of the title salt, C5H6NO(+)·C9H5O6 (-), (I), shows that 4-hy-droxy-pyridine has abstracted an H atom from benzene-1,3,5-tri-carb-oxy-lic acid, yielding a pyridinium cation and carboxyl-ate anion. The two ions form an extensive three-dimensional hydrogen-bonded network throughout the crystal. The hydrogen bonds that comprise the core of the network are considered strong, with O-H⋯...
