Acridinium 2-hy­droxy­benzoate

In the title compound, C13H10N+·C7H5O3 − or (acrH)+(Hsal)−, the asymmetric unit contains one acridinium cation and one salicylate anion. The acridinium N atom is protonated and the carb­oxy­lic acid group of salicylic acid is deprotonated. Both moieties are planar, with an r.m.s. deviation of 0.0127 Å for the acr cation and 0.0235 ° for the sal anion. They are aligned with a dihedral angle of 71.68 (3)° between them. The crystal structure is stabilized by a network of inter­molecular N—H⋯O, O—H⋯O and C—H⋯O hydrogen bonds. C—H⋯π inter­actions are also present

Bis(2,4,6-triamino-1,3,5-triazin-1-ium) pyrazine-2,3-dicarboxyl­ate tetra­hydrate: a synchrotron radiation study

The title compound, 2C3H7N6 +·C6H2N2O4 2−·4H2O or (tataH)2(pzdc)·4H2O, was synthesised by a reaction between pyrazine-2,3-dicarboxylic acid (H2pzdc) as a proton donor and 2,4,6-triamino-1,3,5-triazin (tata) as a proton acceptor. In the crystal structure, an extensive series of O—H⋯O, O—H⋯N, N—H⋯O and N—H⋯N hydrogen bonds generates a three-dimensional framework with the hydrogen bonding involving most donor and acceptor centers. π–π stacking inter­actions are also observed between adjacent triazine rings, with centroid–centroid distances of 3.4994 (8) and 3.5922 (7) Å

Bis(2-amino-6-methyl­pyridinium) trans-diaqua­bis­(pyrazine-2,3-dicarboxyl­ato)cuprate(II) hexa­hydrate

The title compound, (C6H9N2)2[Cu(C6H2N2O4)2(H2O)2]·6H2O, was obtained by the reaction of CuCl2·2H2O with pyrazine-2,3-dicarb­oxy­lic acid (pyzdcH2) and 2-amino-6-methyl­pyridine (2a-6mpy) in aqueous solution. The CuII atom is located on an inversion centre and has an overall octa­hedral coordination environment. Two N and two O atoms from (pyzdc)2− ligands define the equatorial plane and two water mol­ecules are in axial positions, resulting in a typical tetra­gonally Jahn–Teller-distorted environment. Extensive classical O—H⋯O, O—H⋯N and N—H⋯O and non-classical C—H⋯O hydrogen bonds, as well as π–π stacking inter­actions between aromatic rings of the cations [centroid–centroid distance = 3.58 (9) Å], lead to the formation of a three-dimensional supra­molecular structure

An eight-coordinate zinc complex containing the highly pre-organized ligand 1,10-phenanthroline-2,9-dicarboxylic acid: solvothermal synthesis, supramolecular structure and CSD studies

A new anionic coordination complex of Zn(II) containing the highly pre-organized ligand 1,10-phenanthroline-2,9-dicarboxylate (PDA), (H3O)2[Zn(PDA)2]·2CH3NO2·2H2O·(1), has been synthesized by solvothermal methods and characterized by elemental analysis, infrared spectroscopy and single-crystal X-ray diffraction. The last of these techniques revealed a coordination sphere around Zn(II) consisting of four N atoms and four O donors from two 1,10-phenanthroline-2,9-dicarboxylate ligands which features a distorted dodecahedral geometry. The ionic coordination motifs in 1 are held together by intermolecular O―H…O, N―H…O and C―H…O hydrogen bonding, C―H... π and π−π stacking interactions, to produce an extended 2D architecture

X-ray structure of 1D-coordination polymer of copperII bearing 1,4-pyrazine-2,3-dicarboxylic acid and 2-aminopyrimidine

The new 1D-coordination polymer of CuII ion, {(2- apymH)2[Cu(pyzdc)2] .6H2O}n, (2-apym = 2-aminopyrimidine, pyzdcH2 = 1,4- pyrazine-2,3-dicarboxylic acid), was synthesized based on proton transfer mechanism and characterized by elemental analysis, infrared spectroscopy, and single crystal X-ray diffraction. The coordination polymer consists of infinite anionic chains of [Cu(pyzdc)2]2- anion bridged crossing double chain running along a-axis and discrete (2-apymH)+ fragment. The CuII ion is located on inversion centre in the basal plane of an elongated octahedron and two oxygen atoms from adjacent (pyzdc)2-ligands occupy axial position. The interaction between oxygen atoms of water molecules along with the dicarboxylic acid play an important role in the overall supramolecular assembly
