A nickel(II) coordination complex, bis[2,6-bis(1H-benzimidazol-2-yl-κN3)pyridine-κN]nickel(II) sulfate, [Ni(C19H13N5)2]SO4or [Ni(H2L)2]SO4, having four peripheral tetrahedrally oriented N—H donor units, combines with sulfate bridges to create hydrogen-bonded structures of varied dimensionality. The three crystal structures reported herein in the space groupsP212121,I\overline{4} andPccnare defined solely by strong charge-assisted N—H...O hydrogen bonds and contain disordered guests (water and dimethylformamide) that vary in size, shape and degree of hydrophilicity. Two of the compounds are channelled solids with three-dimensional structures, while the third is one-dimensional in nature. In spite of their differences, all three present a striking resemblance to the previously reported anhydrous relative [Guoet al.(2011).Chin. J. Inorg. Chem.27, 1517–1520], which is considered as the reference framework from which all three title compounds are derived. The hydrogen-bonded frameworks are described and compared using crystallographic and topological approaches.

The molecules of all the three compounds are U-shaped with the two aromatic rings inclined at 41.3 (6)° in (I), 42.1 (2)° in (II) and 54.4 (3)° in (III). The molecular conformation of (II) is stabilized by intramolecular C—H...O hydrogen bonds and C—H...π interactions.

The structure also features π–π interactions [Cg...Cg= 3.6970 (14) Å]. In (II), N—H...O hydrogen-bondedR22(8) loops are interconnectedviaπ–π interactions [intercentroid distance = 3.606 (3) Å] to form a one-dimensional architecture running parallel to theaaxis. In (III), adjacentC(4) chains of N—H...O hydrogen-bonded molecules running parallel to [010] are connectedviaC—H...π interactions, forming sheets parallel to theabplane. Neighbouring sheets are linkedviaoffset π–π interactions [intercentroid distance = 3.8303 (16) Å] to form a three-dimensional architecture.

Comparisons are made with some related compounds.

J. Org. Chem.(2011), pp. 2458–2465], are analysed and discussed with a focus on crystal interaction assembly. Both compounds crystallize in the space groupP21/c. The crystal packings are characterized by dimers linked through π–π stacking interactions and intermolecular nonclassical hydrogen bonds, respectively. Additional intermolecular C—H...Cl interactions [in (I) and (II)] and classical O—H...Cl hydrogen bonds [in (II)] are also evident and contribute to generating three-dimensional hydrogen-bonded networks.

The crystals of compound 1 contain neutral and anionic Bmphfp molecules, and form a one-dimensional hydrogen-bonded chain motif. The crystals of compound 2 contain anionic Bmphfp molecules, which form a complex three-dimensional hydrogen-bonded network with the ethylenediamine and water molecules.

The title compounds, C17H14N2O4(I) and C15H12N2O4S (II), possess very similar molecular geometries. In both molecules, the central 1,3,5-trisubstituted dihydropyrazole ring adopts an envelope conformation. The oxobutenoic acid fragment has an almost planarZconformation [r.m.s. deviations of 0.049 and 0.022 Å, respectively, for (I) and (II)] which is determined by the both bond conjugation and the strong intramolecular O—H...O hydrogen bond. The substituents in positions 1 and 3 of the dihydropyrazole ring [oxobutenoic acid and phenyl in (I) and oxobutenoic acid and thienyl in (II)] are nearly coplanar with its basal plane [the corresponding dihedral angles are 6.14 (9) and 2.22 (11)° in (I) and 6.27 (12) and 3.91 (11)° in (II)]. The furyl ring plane is twisted relative to the basal plane of the dihydropyrazole ring by 85.51 (8) and 88.30 (7)° in (I) and (II), respectively. In the crystal of (I), molecules form zigzag hydrogen-bonded chains along [001] by C—H...O hydrogen bonds, which are further packed in stacks along [100]. Unlike (I), the crystal of (II) contains centrosymmetric hydrogen-bonded dimers formed by pairs of C—H...S hydrogen bonds, which are further linked by weak C—H...O hydrogen bonds into a three-dimensional framework.

Crystal structures of twoN-(aryl)arylsulfonamides, namely, 4-methoxy-N-(4-methylphenyl)benzenesulfonamide, C14H15NO3S, (I), andN-(4-fluorophenyl)-4-methoxybenzenesulfonamide, C13H12FNO3S, (II), were determined and analyzed. In (I), the benzenesulfonamide ring is disordered over two orientations, in a 0.516 (7):0.484 (7) ratio, which are inclined to each other at 28.0 (1)°. In (I), the major component of the sulfonyl benzene ring and the aniline ring form a dihedral angle of 63.36 (19)°, while in (II), the planes of the two benzene rings form a dihedral angle of 44.26 (13)°. In the crystal structure of (I), N—H...O hydrogen bonds form infiniteC(4) chains extended in [010], and intermolecular C—H...πarylinteractions link these chains into layers parallel to theabplane. The crystal structure of (II) features N—H...O hydrogen bonds forming infinite one dimensionalC(4) chains along [001]. Further, a pair of C—H...O intermolecular interactions consolidate the crystal packing of (II) into a three-dimensional supramolecular architecture.

The structure of the title compound, [Cd2(C8H4O4)Cl2(C6H15NO3)]n, consists of one-dimensional chains in which each centrosymmetric tetranuclear Cd4Cl4O2cluster is terminated by two chelating triethanolamine (teaH3) ligands but linked to two adjacent clusters through four bridging benzene-1,4-dicarboxylate (bdc) ligands. The tetranuclear Cd4Cl4O2clusters are held togetherviabridging Cl and O atoms. Three directional hydrogen bonds from the multi-podal hydroxy groups of the teaH3ligand stabilize and extend the one-dimensional chains into a three-dimensional framework. All three hydroxy groups of the teaH3ligand form hydrogen bonds, illustrating the fact that the teaH3ligand can serve as an excellent hydrogen-bond donor.

The molecules of the title compounds, C7H8N2OS, (1), C14H13FN2OS, (2), and C17H17FN2O3S, (3), crystallize in the space groupsC2/m,C2/candIa, respectively. Compounds (1) and (2), anS-alkylated derivative of (1), consist of only one symmetry-independent molecule, while (3), anO-alkylated derivative of (2), contains two independent molecules in the asymmetric unit. The molecules of (1) sit on crystallographic mirror planes. In the supramolecular structure of (1), a combination of N—H...O and N—H...S hydrogen bonds creates a molecular strap withC(6) andR22(8) motifs, which is further stabilized by an S...S contact. In the packing of (2), a one-dimensional molecular column is made up of two kinds of dimers. One dimer, with anR22(18) motif, is formed by a pair of C—H...O soft hydrogen bonds and the other, with anR22(8) motif, is producedviaa pair of N—H...O hard hydrogen bonds. In the packing of (3), moleculesAandBform two different types of one-dimensional chain by intermolecular C—H...N hydrogen bonds, and by C...N and O...S contacts, respectively. Two such kinds of chain are connected alternatelyviainterchain C—H...O hydrogen bonds, giving a two-dimensional sheet. Finally, a three-dimensional supramolecular structure is formed through weak intersheet C—H...F hydrogen bonds. The study of the molecular and supramolecular structures of thiouracil derivatives is significant in the development of lipoprotein-associated phospholipase A2inhibitors.

The asymmetric unit of the title compound, 3C10H12N22+·2C10H11N2+·8C6H5NO5P−, contains one and a half naphthalene-1,5-diaminium cations, in which the half-molecule has inversion symmetry, one 5-aminonaphthalen-1-aminium cation and four hydrogen (5-carboxypyridin-3-yl)phosphonate anions. The crystal structure is layered and consists of hydrogen-bonded anionic monolayers between which the cations are arranged. The acid monoanions are organized into one-dimensional chains along the [101] directionviahydrogen bonds established between the phosphonate sites. (C)O—H...Npyhydrogen bonds (py is pyridine) crosslink the chains to form an undulating (010) monolayer. The cations serve both to balance the charge of the anionic network and to connect neighbouring layersviamultiple hydrogen bonds to form a three-dimensional supramolecular architecture.
