2-Cyano-1-methyl-pyridinium iodide.

Project description:The cation in the title compound, C7H7N2 (+)·I(-), is planar (r.m.s. deviation for the nine fitted non-H atoms = 0.040?Å). The crystal packing is best described as undulating layers of cations and anions associated via C-H?I inter-actions.

4-Cyano-1-methyl-pyridinium iodide.

Project description:In the crystal structure of the title compound, C(7)H(7)N(2) (+)·I(-), the cations form inversion-related dimers via weak pairwise C-H⋯N hydrogen bonds. In the dimers, the pyridinium rings are parallel to one another with their mean planes separated by a normal distance of ca 0.28 Å. Weak C-H⋯N inter-actions between adjacent dimers generate a layer lying parallel to (10-1). The remaining H atoms form C-H⋯I inter-actions, which link the layers into a three-dimensional structure.

Salts of 4-[(benzyl-amino)-carbon-yl]-1-methyl-pyridinium and iodide anions with different cation:iodine stoichiometric ratios.

Project description:The two iodide salts, 4-[(benzyl-amino)-carbon-yl]-1-methyl-pyridinium iodide-iodine (2/1), C14H15N2O+·I-·0.5I2, I, and 4-[(benzyl-amino)-carbon-yl]-1-methyl-pyridinium triiodide, C14H15N2O+·I3 -, II, with different cation:iodine atoms ratios were studied. Salt I contains one cation, one iodide anion and half of the neutral I2 mol-ecule in the asymmetric unit (cation:iodine atoms ratio is 1:2). Salt II contains two cations, one triiodide anion (I 3 -) and two half triiodide anions (cation:iodine atoms ratio is 1:3). The NH group forms N-H⋯I hydrogen bonds with the I- anion in the crystal of I or N-H⋯O hydrogen bonds in II where only triiodide anions are present.

2-[(E)-4-(Diethyl-amino)-styr-yl]-1-methyl-pyridinium iodide.

Project description:In the title compound, C(18)H(23)N(2) (+)·I(-), the cation exists in the E configuration with respect to the ethenyl C=C bond.

Project description:In the title compound, C(17)H(20)NO(3) (+)·I(-), the cation exists in the E configuration. The pyridinium and benzene rings are close to coplanar, with a dihedral angle of 7.43?(12)° between them.

A weak intra-molecular C-H?O inter-action generates an S(6) ring motif. In the crystal, the cations are stacked in columns in an anti-parallel manner along the a axis through ?-? inter-actions, with a centroid-centroid distance of 3.7714?(16)?Å. The iodide anion is situated between the columns and linked to the cation by a weak C-H?I inter-action.

(E)-1-Methyl-4-[2-(2-naphth-yl)vin-yl]pyridinium iodide.

Project description:In the title compound, C(18)H(16)N(+)·I(-), the cation is disordered over two orientations related by a 180° rotation about its long axis with occupancies of 0.554?(7) and 0.446?(7). Both disorder components exist in an E configuration. The dihedral angle between the pyridinium ring and the naphthalene ring system is 4.7?(6)° in the major disorder component and 1.6?(8)° in the minor component. In the crystal structure, centrosymmetrically related cations are stacked along the a axis, with significant ?-? inter-actions between the pyridinium ring and the naphthalene ring system [centroid-centroid distance = 3.442?(9)?Å]. The iodide ions are located between adjacent columns of cations. The cations are linked to the iodide ions by C-H?I inter-actions. Weak C-H?? inter-actions involving the methyl group are also observed.
