A new three-dimensional (3D) supramolecular framework, [Ag2(bipy)2(bdc)·4H2O]n 1, has been synthesized by the ultrasonic reaction of Ag2O, bipy and H2bdc (H2bdc = 1,4-benzenedicarboxylic acid; bipy = 4,4’-bipyridine) at room temperature. It exhibits a new 3D supramolecular framework which is built from cationic Ag-bipy chains and anionic bdc-H2O sheets through hydrogen bonds, π · · ·π stacking and C-H· · ·π interactions. Additionally, the photoluminescent and thermal properties of 1 were investigated.

The title compound, [MnCl2(C24H20N6)], has been synthesized and characterized based on the multifunctional ligand 2,5-bis(2,2′-bipyridyl-6-yl)-3,4-diazahexa-2,4-diene (L). The MnIIcentre is five-coordinate with an approximately square-pyramidal geometry. TheLligand acts as a tridendate chelating ligand. The mononuclear molecules are bridged into a one-dimensional chain by two C—H...Cl hydrogen bonds. These chains are assembled into a two-dimensional layer through π–π stacking interactions between adjacent uncoordinated bipyridyl groups. Furthermore, a three-dimensional supramolecular framework is attained through π–π stacking interactions between adjacent coordinated bipyridyl groups.

Two 4,4′-[1,3-phenylenebis(oxy)]dibenzoate anions bridge two 1,10-phenanthroline-chelated ZnIIcations about a center of inversion to generate the dinuclear title compound, [Zn2(C20H12O6)2(C12H8N2)2]·2H2O. The geometry about the ZnIIatom is a distorted octahedron. In the crystal, the molecules are connected by classical O—H...O hydrogen bonds, weak C—H...O hydrogen bonds and C—H...π interactions, forming a three dimensional network. π–π stacking is also observed between aromatic rings of adjacent molecules, centroid–centroid distances are 3.753 (2), 3.5429 (16) and 3.5695 (17) Å.

A self-assembled, tetrameric water cluster stabilised by carboxyl-bridging has been characterised by X-ray diffraction studies and thermogravimetric analysis. Every water cluster is connected strongly via hydrogen bonds to four carboxyl oxygens of a terephthalate anion. The water rings are stable at room temperature, but when thermally decomposed, the water loss is irreversible.

The cation-templated self-assembly of 1,4-bis(2-methyl-1H-imidazol-1-yl)butane (bmimb) with CuSCN gives rise to a novel two-dimensional network, namelycatena-poly[2,2′-dimethyl-1,1′-(butane-1,4-diyl)bis(1H-imidazol-3-ium) [tetra-μ2-thiocyanato-κ4S:S;κ4S:N-dicopper(I)]], {(C12H20N4)[Cu2(NCS)4]}n. The CuIcation is four-coordinated by one N and three S atoms, giving a tetrahedral geometry. One of the two crystallographically independent SCN−anions acts as a μ2-S:Sbridge, binding a pair of CuIcations into a centrosymmetric [Cu2(NCS)2] subunit, which is further extended into a two-dimensional 44-sql net by another kind of SCN−anion with an end-to-end μ2-S:Ncoordination mode. Interestingly, each H2bmimb dication, lying on an inversion centre, threads through one of the windows of the two-dimensional 44-sql net, giving a pseudorotaxane-like structure. The two-dimensional 44-sql networks are packed into the resultant three-dimensional supramolecular framework through bmimb–SCN N—H...N hydrogen bonds.

The title compounds, C11H10N4O (HL1) and C11H10N4O (HL2), are pyridine 2-ylmethyl and 4-ylmethyl derivatives, respectively, of pyrazine-2-carboxamide. HL1 was measured at 153 K and crystallized in the monoclinic space groupP21/cwithZ= 4. There has been a report of the same structure measured at room temperature but assumed to crystallize in the triclinic space groupP-1 withZ= 4 [Sasanet al.(2008).Monatsh. Chem.139, 773–780]. In HL1, the pyridine ring is inclined to the pyrazine ring by 61.34 (6)°, while in HL2 this dihedral angle is 84.33 (12)°. In both molecules, there is a short N—H...N interaction involving the pyrazine carboxamide unit. In the crystal of HL1, molecules are linked by N—H...N hydrogen bonds, forming inversion dimers with anR22(10) ring motif. The dimers are linkedviabifurcated-acceptor C—H...O hydrogen bonds, forming sheets lying parallel to (102). The sheets are linkedviaC—H...N hydrogen bonds, forming a three-dimensional structure. In the crystal of HL2, molecules are linked by N—H...N and C—H...N hydrogen bonds to form chains propagating along [010]. The chains are linkedviaC—H...O hydrogen bonds, forming sheets lying parallel to (100). Within the sheets there are π–π interactions involving neighbouring pyrazine rings [inter-centroid distance = 3.711 (15) Å]. Adjacent sheets are linkedviaparallel slipped π–π interactions involving inversion-related pyridine rings [inter-centroid distance = 3.6395 (17) Å], forming a three-dimensional structure.

In the title salt, C6H9ClN3+·C6H3O4S−, the cations and anions are linkedviaO—H...O and N—H...O hydrogen bonds, formingR66(37) ring motifs that are interconnected with each other, producing sheets. Separate parallel inversion-related sheets are linked through N—H...N and π–π stacking interactions [centroid–centroid distance = 3.5414 (13) Å], forming double layers parallel to (101). Weak C—H...O and C—H...S hydrogen bonds, as well as C—H...π interactions, connect the double layers into a three-dimensional network.

The crystal structures of twoN-(arylsulfonyl)arylamides, namelyN-(3-fluorobenzoyl)benzenesulfonamide, C13H10FNO3S, (I), andN-(3-fluorobenzoyl)-4-methylbenzenesulfonamide, C14H12FNO3S, (II), are described and compared with related structures. The dihedral angle between the benzene rings is 82.73 (10)° in (I) compared to 72.60 (12)° in (II). In the crystal of (I), the molecules are linked by C—H...O and C—H...π interactions, resulting in a three-dimensional grid-like architecture, while C—H...O interactions lead to one-dimensional ribbons in (II). The crystals of both (I) and (II) feature strong but non-structure-directing N—H...O hydrogen bonds withR22(8) ring motifs. The structure of (I) also features π–π stacking interactions.
