4,4'-Bis[2-(3,5-dimeth-oxy-phen-yl)ethen-yl]biphen-yl.

ABSTRACT: The title compound, C(32)H(30)O(4), crystallizes with three different conformers of the same mol-ecule in the asymmetric unit, which explains the unusually large unit cell volume. The supra-molecular structure is based on inter-actions involving the meth-oxy groups [C?O contacts between 3.090?(2) and 3.204?(2)?Å, and C-H?O contacts between (normalized) 2.40 and 2.71?Å], ?-? stacking of the electron-rich meth-oxy-substituted rings [centroid-centroid distances of 3.6454?(9)-3.738?(1)?Å] and C-H?? contacts (normalized, 2.62-2.97Å).

The title compound, C(32)H(30)O(4), crystallizes with three different conformers of the same mol-ecule in the asymmetric unit, which explains the unusually large unit cell volume. The supra-molecular structure is based on inter-actions involving the meth-oxy groups [C⋯O contacts between 3.090 (2) and 3.204 (2) Å, and C-H⋯O contacts between (normalized) 2.40 and 2.71 Å], π-π stacking of the electron-rich meth-oxy-substituted rings [centroid-centroid distances of 3.6454 (9)-3.738 (1) Å] and C-H⋯π ...[more]

3,5-Dimeth-oxy-4'-methyl-biphen-yl.

Project description:The title compound, C15H16O2, crystallizes with three independent mol-ecules in the asymmetric unit. The intra-molecular torsion angle between the aromatic rings of each mol-ecule are -36.4 (3), 41.3 (3) and -37.8 (3)°. In the crystal, the complicated packing of the mol-ecules forms wave-like layers along the b and c axes. The mol-ecules are connected via extensive meth-oxy-phenyl C-H⋯π inter-actions. A weak C-H⋯O hydrogen-bonding network also exists between meth-oxy O atoms and aromatic or meth-oxy H atoms.

N-(3,5-Dimeth-oxy-phen-yl)benzamide.

Project description:The title compound, C(15)H(15)NO(3), was prepared by stirring benzoyl chloride with 3,5-dimeth-oxy-aniline in dioxane at ambient temperature. The dimeth-oxy-phen-yl-amide segment of the mol-ecule is almost planar, with a C-N-C=O torsion angle of -4.1?(4)°. The two benzene rings are inclined at an angle of 76.66?(13)°. In the crystal, inter-molecular N-H?O inter-actions generate centrosymmetric dimers..

Bis(3,5-dimeth-oxy-phen-yl)phosphinic acid.

Project description:In the crystal structure of the title compound, C(16)H(19)O(6)P, inter-molecular O-H?O inter-actions link the mol-ecules into chains parallel to the b axis. These chains are linked by C-H?? and ?-? inter-actions [centroid-centroid distance = 3.7307?(29)?Å] into a three-dimensional network. The dihedral angle between the benzene rings is 73.5?(1)°. The C and O atoms of all four methoxy groups lie very close to the mean planes of their attached rings; the C atoms are 0.055?(2)-0.1038?(1)?Å out of the mean plane of the attached rings.

3,3'-Bis(chloro-meth-yl)-4,4'-dieth-oxy-1,1'-biphen-yl.

Project description:The asymmetric unit of the title compound, C18H20Cl2O2, consists of a half-mol-ecule, the other half being generated by an inversion center, located at the mid-point of the benzene-benzene bond. Except for the two Cl atoms, all other atoms of the compound are nearly coplanar, with the atomic displacements from the mol-ecular mean plane ranging from 0.0037 (19) to 0.071 (2) Å. The two Cl atoms are in trans positions and are displaced with respect to the mean plane by 1.687 (2) and -1.693 (3) Å. The crystal packing is governed by van der Waals inter-actions.

Bis(2,4-dimeth-oxy-phen-yl)(phen-yl)phosphine selenide.

Project description:In the title mol-ecule, C(22)H(23)O(4)PSe, the P atom has a distorted tetra-hedral environment formed by the selenide atom [P=Se = 2.1219?(5)?Å] and three aryl rings. The orientations of the meth-oxy groups in the two 2,4-dimeth-oxy-phenyl ligands are distinct, as seen from the torsion angles: C-C-O-C = 14.7?(3) and 175.97?(17)° in one ligand, and -9.1?(2) and 5.1?(3)° in the other. In the crystal, weak inter-molecular C-H?Se inter-actions link the mol-ecules into zigzag chains propagated in [010].

4,4'-Bis[(E)-(2,3-diiodo-prop-2-en-1-yl)-oxy]biphen-yl.

Project description:Iodine adds across both triple bonds of 4,4'-bis-(prop-2-yn--yl-oxy)biphenyl, yielding the 4,4'-bis-(2,3-diiodo-all-yloxy)biphenyl title compound, C(18)H(14)I(4)O(2); the 2,3-diiodo-ally-oxy substituents have the I atoms in an E configuration. In the biphenyl portion of the mol-ecule, the aromatic rings are inclined by 37.8 (2)°.

1-(2-Hy-droxy-3,5-dimeth-oxy-phen-yl)ethanone.

Project description:In title compound, C(10)H(12)O(4), all of the non-H atoms lie approximately in a plane with the largest deviation being 0.061?(2)?Å. An intra-molecular O-H?O hydrogen bond generates an S(6) ring motif. No classical inter-molecular hydrogen bonding occurs, with only van der Waals forces stabilizing the crystal structure.

In addition, the conformations of the pairs of methyl groups and their counterparts differ from each other though their environment is very similar. In the crystal, weak C-H?O inter-actions occur.

4,4'-Bis(benzimidazol-1-yl)biphen-yl.

Project description:The mol-ecule of the title compound, C(26)H(18)N(4), resides on a crystallographic inversion centre with a dihedral angle of 44.94 (5)° between the benzimidazole ring system and the benzene ring. The primary hydrogen bond is C-H⋯N and inversion-related pairs of these generate a chain of rings along the c-axis direction; π⋯π stacking involving the benzimidazole groups with inter-planar separations of ca 3.4 Å complete the inter-actions.

3,5-Dimeth-oxy-2-[(4-propyl-phen-yl)imino-meth-yl]phenol.

Project description:The title compound, C(18)H(21)NO(3), crystallizes in the phenol-imine tautomeric form, with the H atom attached to oxygen rather than on nitro-gen. This H atom is involved in a strong intra-molecular O-H⋯N hydrogen bond. A C-H⋯π inter-action is also present. The dihedral angle between the aromatic rings is 12.23 (7)°.
