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

ABSTRACT: 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.

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⋯π and π-π 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 ...[more]

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

Project description: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).

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(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].

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.

Project description:In the title mol-ecule {systematic name: [2,7-dimethoxy-8-(4-phenoxybenzoyl)naphthalen-1-yl](4-phenoxyphenyl)methan-one}, C(38)H(28)O(6), the 4-phen-oxy-benzoyl units adopt a syn orientation with respect to the naphthalene ring system. The inter-nal benzene rings, A and B, make dihedral angles of 86.72?(5) and 79.22?(5)° with the naphthalene ring system. The two terminal benzene rings, C and D, of the 4-phen-oxy-benzoyl groups are twisted with respect to benzene rings A and B, with dihedral angles of A/C = 62.72?(8) and B/D = 87.61?(6)°. In the crystal, H atoms in the naphthalene system make two types of inter-molecular C-H?O inter-actions with the carbonyl O atom and the phenyl etheral O atom of neighbouring mol-ecules. Mol-ecules are further linked by C-H?? inter-actions involving a H atom of terminal benzene ring D and the ?-system of the inter-nal benzene ring A, forming dimers centered about an inversion center.
