Crystal structure of triphenylphosphonium-meth-yl-enetrifluoroborate.

ABSTRACT: The title compound, C₁₉H₁₇BF₃P {alternative name: triphen-yl[(tri-fluoro-boran-yl)meth-yl]phosphanium}, was formed by the reaction of tri-phenyl-phosphine with potassium iodo-methyl-tri-fluoro-borate. The mol-ecule features a nearly staggered conformation along the P-C bond and a less than staggered conformation along the C-B bond. In the crystal, weak C-H⋯F hydrogen bonds between the meta-phenyl C-H groups and the tri-fluoro-borate B-F groups form chains of R₂²(16) rings along [100]. These chains are are further stabilized by weak C-H⋯π inter-actions. A weak intra-molecular C-H⋯F hydrogen bond is also observed.

Crystal structure of benz-yl(meth-yl)phen-yl[(piperidin-1-ium-1-yl)meth-yl]silane bromide.

Project description: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 anion. The crystal packing shows the dominant inter-molecular inter-action to be the electrostatic attraction between the ammonium cation and the bromide anion.

Crystal structure of 3-(hy-droxy-meth-yl)chromone.

Project description:In the title compound, C10H8O3 (systematic name 3-hy-droxy-methyl-4H-chromen-4-one), the fused-ring system is slightly puckered [dihedral angle between the rings = 3.84 (11)°]. The hy-droxy O atom deviates from the heterocyclic ring by 1.422 (1) Å. In the crystal, inversion dimers linked by pairs of O-H⋯O hydrogen bonds generate R 2 (2)(12) loops. The dimers are linked by aromatic π-π stacking [shortest centroid-centroid distance = 3.580 (3) Å], and C-H⋯O hydrogen bonds, generating a three-dimensional network.

Project description:In the title molecular salt, C12H14N3 (+)·NH4 (+)·2Cl(-), the central, secondary-amine, N atom is protonated. The bis-[(pyridin-2-yl)meth-yl]ammonium and ammonium cations both lie across a twofold rotation axis. The dihedral angles between the planes of the pyridine rings is 68.43 (8)°. In the crystal, N-H⋯N and N-H⋯Cl hydrogen bonds link the components of the structure, forming a two-dimensional network parallel to (010). In addition, weak C-H⋯Cl hydrogen bonds exist within the two-dimensional network.

Crystal structure of 1,3-bis-(1H-benzotriazol-1-yl-meth-yl)benzene.

Project description:The mol-ecular structure of the title compound, C20H16N6, contains two benzotriazole units bonded to a benzene nucleus in a meta configuration, forming dihedral angles of 88.74 (11) and 85.83 (10)° with the central aromatic ring and 57.08 (9)° with each other. The three-dimensional structure is controlled mainly by weak C-H⋯N and C-H⋯π inter-actions. The mol-ecules are connected in inversion-related pairs, forming the slabs of infinite chains that run along the [-110] and [110] directions.

Crystal structure of (E)-2-{[(4-anilinophen-yl)imino]-meth-yl}phenol.

Project description:The title compound, C19H16N2O, crystallized with two independent mol-ecules (A and B) in the asymmetric unit. There is an intra-molecular O-H⋯N hydrogen bond in each mol-ecule with the phenol ring being inclined to the central benzene ring by 4.93 (14) and 7.12 (14)° in mol-ecules A and B, respectively. The conformation of the two mol-ecules differs essentially in the orientation of the terminal amino-phenyl ring with respect to the central benzene ring; this dihedral angle is 50.51 (4)° in mol-ecule A and 54.61 (14)° in mol-ecule B. The two outer aromatic rings are inclined to one another by 51.39 (14) and 49.88 (14)° in mol-ecules A and B, respectively. In the crystal, mol-ecules are connected by N-H⋯O hydrogen bonds generating -A-B-A-B- zigzag chains extending along [010]. The chains are linked via C-H⋯π inter-actions involving neighbouring A mol-ecules, forming slabs lying parallel to (100).
