In an attempt to brominate 1,4-dipropoxy-9,10-anthraquinone, a mixture of products, including the title compound, C14H7BrO4, was obtained. The molecule is essentially planar (r.m.s. deviation = 0.029 Å) and two intramolecular O—H...O hydrogen bonds occur. In the crystal, the molecules are linked by weak C—H...O hydrogen bonds, Br...O contacts [3.240 (5) Å], and π–π stacking interactions [shortest centroid–centroid separation = 3.562 (4) Å], generating a three-dimensional network.

Molecules of the title compound, C12H13NO5, are linked into chains via weak C—H...π(allyl) interactions and these chains are linked into sheets via C—H...O contacts; the sheets, in turn, are interconnected via carbonyl–carbonyl and nitro–π stacking interactions to form a three-dimensional crystal structure.

In the title compound, [Cd2(C9H6O5)2(H2O)2] n , the crystallographically distinct CdII cations are coordinated in pentagonal–bipyramidal and octahedral fashions. The 2-(carboxymethoxy)benzoate (cmb) ligands connect the Cd atoms into [Cd2(cmb)2(H2O)2)] n coordination polymer ribbons that are oriented along the a-axis direction. Supramolecular layers are formed parallel to (01\overline{1}) by O—H...O hydrogen bonding between the ribbons. The supramolecular three-dimensional crystal structure of the title compound is then constructed by π–π stacking interactions with a centroid–centroid distance of 3.622 (2) Å between cmb ligands in adjacent layer motifs.

In the crystal of the title polymeric complex, {[CoCa(C7H3NO4)2(H2O)4]·2H2O} n (1), the CoII ion is N,O,O′-chelated by two pyridine-2,6-dicarboxylate anions in a distorted N2O4 octahedral geometry, and two carboxylate O atoms of pyridine-2,6-dicarboxylate anions bridge tetraaquacalcium(II) units to form polymeric chains propagating along the b-axis direction. In the crystal, O—H...O and C—H...O hydrogen bonds, and offset π–π stacking interactions [intercentroid distances = 3.551 (1) and 3.746 (1) Å] involving inversion-related pyridine rings link the polymeric chains and lattice water molecules to form a supramolecular three-dimensional framework.

In the title coordination polymer, {[CuCl2(C27H26N6O2S)]·CH3CN} n , the copper(II) ion is fivefold coordinated, with an almost perfect square-pyramidal coordination sphere. In the equatorial plane, it is ligated to a pyridine N atom and an N atom of the triazole unit and to two Cl− ions, while the apical position is occupied by the carbonyl O atom of the tert-butyl carbamate group. In the crystal, the polymer chains propagate in the [11-1] direction, with the acetonitrile solvent molecules linked to the chain by C—H...N hydrogen bonds. The chains are linked by C—H...Cl hydrogen bonds forming sheets parallel to the plane (011). The crystal packing is further consolidated by C—H...π interactions and offset π–π stacking interactions [intercentroid distance = 3.6805 (15) Å], forming a three-dimensional supramolecular structure.

The reaction of Cu(NO3)2·3H2O with 2,4′-oxybis(benzoic acid) and 4,4′-bipyridine under hydrothermal conditions produced a new mixed-ligand two-dimensional copper(II) coordination polymer, namely poly[[(μ-4,4′-bipyridine-κ2 N,N′)[μ-2,4′-oxybis(benzoato)-κ4 O 2,O 2′:O 4,O 4′]copper(II)] monohydrate], {[Cu(C14H8O5)(C10H8N2)]·H2O} n , which was characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis and single-crystal X-ray diffraction. The X-ray diffraction crystal structure analysis reveals that the CuII ions are connected to form a two-dimensional wave-like network through 4,4′-bipyridine and 2,4′-oxybis(benzoate) ligands. The two-dimensional layers are expanded into a three-dimensional supramolecular structure through intermolecular O—H...O and C—H...O hydrogen bonds. Furthermore, magnetic susceptibility measurements indicate that the complex shows weak antiferromagnetic interactions between adjacent CuII ions.

In the title molecular salt, C22H22O2P+·PF6−, the side chain of the cation adopts ananti–gaucheconformation [P—C—C—C and C—C—C—C torsion angles = −179.11 (10) and −77.18 (16)°, respectively]. In the crystal, the cations are linked into carboxylic acid inversion dimers by pairs of O—H...O hydrogen bonds. Weak C—H...F and C—H...(F,F) hydrogen bonds connect the components into a three-dimensional network, but there are no aromatic π–π stacking interactions.
