In the crystal structure of the title organic proton-transfer complex, 2C12H11N2 +·C7H4O5S2−·3H2O, the cations form one-dimensional chains via intermolecular N—H...N hydrogen bonds and these chains, in turn, form a two-dimensional network through π–π stacking interactions. In addition, the anions and water molecules are connected into a two-dimensional hydrogen-bonded network through intermolecular O—H...O hydrogen bonds. The two motifs result in sheets of cations and anions stacked alternately.

Abstract A pair of two-dimensional (2D) isostructural coordination polymers (CPs), {[Co(2,3-qldc)(H2O)]} n (1) and {[Mn(2,3-qldc)(H2O)]} n (2), where 2,3-H2qldc = quinoline-2,3-dicarboxylic acid, were hydrothermally synthesized and characterized through IR spectroscopy, elemental and thermal analysis, power X-ray diffraction, and single-crystal X-ray diffraction. The results have revealed that the fully deprotonated 2,3-H2qldc ligand connects the Co(II)/Mn(II) atoms with a μ 3-bridge to form a square-wave 2D network, which is further extended into 3D stacks through O–H···O, C–H···O hydrogen bonds and π···π stacking interactions. Topologically, 1 or 2 can be simplified as a 4-connected sql type with a Schläfli symbol {44·62} and a Shubnikov tetragonal plane net, or as a 3-connected fes type with a Schläfli symbol {4·82} and a Shubnikov plane net. The thermal stability and the solid state fluorescence properties of 1 and 2 were investigated.

The title compound, [Na2(C6H5N2O2)2(C6H6N2O2)4], is a centrosymmetric coordination dimer based on the sodium(I) salt ofN-hydroxypicolinamide. The molecule has an {Na2O6(μ-O)2} core with two bridging carbonyl O atoms and two hydroxamate O atoms of two mono-deprotonated residues ofN-hydroxypicolinamide, while two neutralN-hydroxypicolinamide molecules are coordinated in a monodentate manner to each sodium ionviathe carbonyl O atoms [the Na—O distances range from 2.3044 (2) to 2.3716 (2) Å]. The pentacoordinated sodium ion exhibits a distorted trigonal–pyramidal coordination polyhedron. In the crystal, the coordination dimers are linked into chains along thecaxisviaN—H...O and N—H...N hydrogen bonds; the chains are linked into a two-dimensional framework parallel to (100)viaweak C—H...O and π–π stacking interactions.

The one- and two-dimensional polymorphic cadmium polycarboxylate coordination polymers,catena-poly[bis[μ2-2-(2-methyl-1H-benzimidazol-1-yl)acetato-κ3N3:O,O′]cadmium(II)], [Cd(C10H9N2O2)2]n, and poly[bis[μ2-2-(2-methyl-1H-benzimidazol-1-yl)acetato-κ3N3:O,O′]cadmium(II)], also [Cd(C10H9N2O2)2]n, were prepared under solvothermal conditions. In each structure, each CdIIatom is coordinated by four O atoms and two N atoms from four different ligands. In the former structure, two crystallographically independent CdIIatoms are located on twofold symmetry axes and doubly bridged in a μ2-N:O,O′-mode by the ligands into correspondingly independent chains that run in the [100] and [010] directions. Chains containing crystallographically related CdIIatoms are linked into sheetsviaπ–π stacking interactions. Sheets containing one of the distinct types of CdIIatom are stacked perpendicular to [001] and alternate with sheets containing the other type of CdIIatom. The second complex is a two-dimensional homometallic CdII(4,4) net structure in which each CdIIatom is singly bridged to four neighbouring CdIIatoms by four ligands also acting in a μ2-N:O,O′-mode. A square-grid network results and the three-dimensional supramolecular framework is completed by π–π stacking interactions between the aromatic ring systems.
