2,2'-[2,3,5,6-Tetra-methyl-p-phenyl-ene-bis(methyl-enethio)]bis-(pyridine N-oxide).

ABSTRACT: Mol-ecules of the title compound, C(22)H(24)N(2)O(2)S(2), lie across centres of inversion. The two thio-pyridine N-oxide groups adopt a stepped trans configuration with respect to the benzene ring, by virtue of the symmetry. The oxopyridinium ring forms a dihedral angle of 79.9?(2)° with the benzene ring. The crystal structure is stabilized by a strong ?-? inter-action between the pyridinium rings of adjacent mol-ecules [ring centroid-centroid distance = 3.464?(3)?Å].

Mol-ecules of the title compound, C(22)H(24)N(2)O(2)S(2), lie across centres of inversion. The two thio-pyridine N-oxide groups adopt a stepped trans configuration with respect to the benzene ring, by virtue of the symmetry. The oxopyridinium ring forms a dihedral angle of 79.9 (2)° with the benzene ring. The crystal structure is stabilized by a strong π-π inter-action between the pyridinium rings of adjacent mol-ecules [ring centroid-centroid distance = 3.464 (3) Å]. ...[more]

Project description:The heterocylic ligand of the polymeric title compound, [CdI(2)(C(22)H(30)N(4))], links two adjacent CdI(2) units, forming a chain running parallel to [[Formula: see text]01]. The Cd(II) atom is located on a twofold rotation axis and shows a distorted tetra-hedral CdI(2)N(2) coordination. The mid-point of the benzene ring of the ligand lies on a center of inversion. There are no classical hydrogen-bonding inter-actions present.

Project description:The asymmetric unit of the title compound, C(24)H(22)O(4), contains one half-mol-ecule, the other half being generated by a crystallographic center of inversion. The central benzene ring makes a dihedral angle of 72.49?(5)° with the terminal benzene ring. In the crystal, adjacent mol-ecules are linked through C-H?O inter-actions, forming a sheet structure parallel to the bc plane. The sheets are stacked along the a axis via ?-? inter-actions formed between the terminal benzene rings [centroid-centroid separation = 3.7276?(6)?Å].

Project description:The title imidazolium-based ionic-liquid salt, C(18)H(24)N(4) (2+)·2PF(6) (-), has the cation lying about a center of inversion. The five-membered imidazole ring is disordered over two positions (the methyl substituents are ordered).

Project description:The asymmetric unit of the title compound, (C(14)H(20)N(4))[Ag(CN)(2)](2), contains one-half of a centrosymmetric 2,2'-(p-phenyl-ene)bis-(1,4,5,6-tetra-hydro-pyrimidinium) (H(2)btb) cation and one [Ag(CN)(2)](-) anion.

In the crystal structure, each H(2)btb cation links four [Ag(CN)(2)](-) anions via N-H?N hydrogen bonds into a one-dimensional ribbon.

2,2',2'',2'''-[Pyridine-2,6-diylbis(methyl-ene-nitrilo)]tetra-ethanol.

Project description:In the crystal structure of the title compound C(15)H(27)N(3)O(4), the mol-ecule is located on a twofold axis and the asymmetric unit contains one half-mol-ecule, with one N and one C atom lying on the rotation axis. The pyridine ring is the hydrogen-bond acceptor, while two hydroxyl O atoms act as hydrogen-bond donors in intra-molecular O-H⋯N and intermolecular O-H⋯N and O-H⋯O hydrogen bonds, thereby forming a closed hydrogen-bonded cage.

[1,4-Phenyl-enebis(methyl-ene)]bis-(tri-phenyl-phospho-nium) bis-(tetra-fluoro-borate).

Project description:The crystal structure of the title salt, C(44)H(38)P(2) (2+)2BF(4) (-), consists of discrete dications inter-laced with the BF(4) (-) counter-ions. In each cation, both phospho-nium groups lie on the same side of the plane of the central benzene ring. The tetra-fluoro-borate anions are involved in intensive thermal motion, thus some B-F bond lengths [range 1.329?(6) to 1.391?(6)?Å] deviate significantly from their standard values.

2,2'-[2,3,5,6-Tetra-methyl-p-phenyl-enebis-(methyl-eneoxy)]dibenzoic acid.

Project description:The asymmetric unit of the title compound, C(26)H(26)O(6), contains only a half-mol-ecule, the other half being generated by an inversion center. The two carboxy-phenoxy-methyl units occupy the 1,4-positions of the central aromatic ring. The central ring and the six linked C atoms are almost planar, with a maximum deviation of 0.0286?(17)?Å, and the plane makes a dihedral angle of 75.50?(6)° with the benzene ring. In the crystal, strong O-H?O hydrogen bonds between the carboxyl groups of adjacent mol-ecules and C-H?? inter-actions link the mol-ecules into zigzag chains along (220) and (10); the two types of chain are arranged alternately, forming a three-dimensional framework.
