2,3,6,7-Tetra-meth-oxy-9,10-anthra-quinone.

ABSTRACT: Mol-ecules of the title compound, C(18)H(16)O(6), are almost planar [maximum deviation = 0.096?(4)?Å] and reside on crystallographic centres of inversion. They adopt a conformation in which the C(meth-yl)-O bonds are directed along the mol-ecular short axis [C-C-O-C torsion angles of -175.3?(3) and 178.2?(3)°]. In the crystal, mol-ecules adopt a slipped-parallel arrangement with ?-? stacking inter-actions along the a axis with an inter-planar distance of 3.392?(4)?Å. Weak C-H?O inter-actions link the mol-ecules into sheets parallel to (10-2).

Crystal structure of 1,4-dieth-oxy-9,10-anthra-quinone.

Project description:The asymmetric unit of the title compound, C18H16O4, contains two crystallographically independent mol-ecules. The anthra-quinone ring systems are slightly bent with dihedral angles of 2.33 (8) and 13.31 (9)° between the two terminal benzene rings. In the crystal, the two independent mol-ecules adopt slipped-parallel π-overlap with an average inter-planar distance of 3.45 Å, forming a dimer; the centroid-centroid distances of the π-π inter-actions are 3.6659 (15)-3.8987 (15) Å. The mol-ecules are also linked by C-H⋯O inter-actions, forming a tape structure along the a-axis direction. The crystal packing is characterized by a dimer-herringbone pattern.

Tetra-methyl anthracene-2,3,6,7-tetra-carboxyl-ate-tetra-methyl 9,10-dihydro-9,10-dioxoanthracene-2,3,6,7-tetra-carboxyl-ate (1/1).

Project description:In the title co-crystal, C(22)H(16)O(10)·C(22)H(18)O(8), the independent tetra-methyl 9,10-dihydro-9,10-dioxoanthracene-2,3,6,7-tetra-carboxyl-ate, (I), and tetra-methyl anthracene-2,3,6,7-tetra-carboxyl-ate, (II), components occupy separate crystallographic inversion centers. In (II), the dihedral angles between the mean aromatic plane and the two independent carboxyl-ate planes are 41.32 (10) and -38.35 (10)°. The methyl-carboxyl-ate groups of (I) are disordered, with each resolvable into two groups. In the least disordered carboxyl-ate, the apparent angles between the mean aromatic plane and the two partial carboxyl-ate planes [site occupations = 0.510 (3) and 0.490 (3)] are 16.8 (3) and 23.3 (3)°. In the highly disordered group, the apparent angles between the mean aromatic plane and the two partial carboxyl-ate planes [site occupations = 0.510 (3) and 0.490 (3)] are 78.3 (3) and -74.1 (3)°. In addition, this extreme disorder leads to an artificially elongated C(aromatic)-C(carbox-yl) bond.

Crystal structure of 2-bromo-1,4-dihy-droxy-9,10-anthra-quinone.

Project description:In an attempt to brominate 1,4-diprop-oxy-9,10-anthra-quinone, a mixture of products, including the title compound, C14H7BrO4, was obtained. The mol-ecule is essentially planar (r.m.s. deviation = 0.029?Å) and two intra-molecular O-H?O hydrogen bonds occur. In the crystal, the mol-ecules are linked by weak C-H?O hydrogen bonds, Br?O contacts [3.240?(5)?Å], and ?-? stacking inter-actions [shortest centroid-centroid separation = 3.562?(4)?Å], generating a three-dimensional network.

2,3,6,7-Tetra-kis(bromo-meth-yl)naphthalene.

Project description:The title compound, C(14)H(12)Br(4), crystallizes with imposed inversion symmetry. In the crystal, the mol-ecules pack in layers parallel to (10). The layers involve two Br?Br and one H?Br contact. Between the layers, one contact each of types Br?Br, H?Br and Br?? is observed.

1-Meth-oxy-4-methyl-9,10-anthraquinone.

Project description:The non-H atoms of the title compound, C(16)H(12)O(3), lie approximately in a common plane (r.m.s. deviation = 0.032?Å). The methyl C atom is forced away from the carbonyl O atom which can be seen by the widened C(fused ring)-C(benzene)-C(meth-yl) angle of 125.8?(2)°.

Crystal structures of 1-hy-droxy-4-prop-yloxy-9,10-anthra-quinone and its acetyl derivative.

Project description:1-Hy-droxy-4-prop-yloxy-9,10-anthra-quinone, C17H14O4, (I), and its acetyl derivative, 4-acet-yloxy-4-prop-yloxy-9,10-anthra-quinone, C19H16O5, (II), were synthesized from the commercially available dye quinizarin. In both compounds, the anthra-quinone frameworks are close to planarity. There is a large difference in the conformation of the prop-yloxy group; the mol-ecule of (I) adopts a gauche conformation [O-C-C-C = -64.4 (2)°], although the mol-ecule of (II) takes a trans-planar conformation (zigzag) [O-C-C-C = 176.1 (3)°]. In the mol-ecule of (I), there is an intra-molecular O-H⋯O hydrogen bond. In both crystals, the mol-ecules are linked by C-H ⋯O hydrogen bonds. A difference in the mol-ecular arrangements of (I) and (II) is found along the stacking directions.

2',3,4,4'-Tetra-meth-oxy-chalcone.

Project description:IN THE TITLE COMPOUND [SYSTEMATIC NAME: 1-(2,4-dimethoxyphenyl)-3-(3,4-dimethoxyphenyl)prop-2-en-1-one], C(19)H(20)O(5), the dihedral angle between the benzene rings is 26.88?(5)°. One of the meth-oxy groups is twisted slightly away from the plane [C-O-C-C torsion angle = -12.8?(3)°] while the others are almost co-planer [C-O-C-C torsion angles = -3.2?(3), 2.6?(3) and -3.6?(3)°]. The crystal packing is stabilized by inter-molecular C-H?O inter-actions. A weak intra-molecular C-H?O inter-action occurs.

Project description:The title compound, C(16)H(12)O(4), exists as planar molecules in the solid state (r.m.s. deviation of 0.02?Å in one mol-ecule and 0.07?Å in the second independent mol-ecule comprising the asymmetric unit).
