The title compound, {(C6H14N2O2)[Cu2Cl6(H2O)]}n, consists of 1,4-dihydroxy-1,4-diazoniabicyclo[2.2.2]octane dications and one-dimensional inorganic anionic {[Cu2Cl6(H2O)]2−}nchains in which both five-coordinate [CuCl3(H2O)]−and five-coordinate [CuCl3]−units exist. These two distinct type of unit are linked together by one chloride ion and are bridged across centres of inversion to further units of their own type through two chloride ions, giving rise to novel polymeric zigzag chains parallel to thecaxis. The chains are connected by O—H...Cl hydrogen bonds to produceR24(16) ring motifs, resulting in two-dimensional layers parallel to theacplane. These layers are linked into a three-dimensional framework with the organic cationsviaO—H...Cl hydrogen bonds. Hydrogen bonding between the chains, and between the chains and the organic cations, provides stability to the crystal structure.

The structure of the title compound, C13H12N3 +·ClO4 −, reveals a twofold axis through the ring N and para-C atoms; a twofold rotation axis also passes through the Cl atom. The structure of the organic fragment is similar to that of homologous heterocyclic systems. The organic cations and perchlorate anions self-assemble in the solid state through C—H...O and N—H...O hydrogen bonds, leading to a two-dimensional layer parallel to the (112) plane. The layers are stacked along the c axis through offset π–π interactions between cations from different layers (the distance between the planes through two cations is 3.35 Å), resulting in a three-dimensional supramolecular architecture.

The one-dimensional coordination polymercatena-poly[diaqua(sulfato-κO)copper(II)]-μ2-glycine-κ2O:O′], [Cu(SO4)(C2H5NO2)(H2O)2]n, (I), was synthesized by slow evaporation under vacuum of a saturated aqueous equimolar mixture of copper(II) sulfate and glycine. On heating the same blue crystal of this complex to 435 K in an oven, its aspect changed to a very pale blue and crystal structure analysis indicated that it had transformed into the two-dimensional coordination polymer poly[(μ2-glycine-κ2O:O′)(μ4-sulfato-κ4O:O′:O′′:O′′)copper(II)], [Cu(SO4)(C2H5NO2)]n, (II). In (I), the CuIIcation has a pentacoordinate square-pyramidal coordination environment. It is coordinated by two water molecules and two O atoms of bridging glycine carboxylate groups in the basal plane, and by a sulfate O atom in the apical position. In complex (II), the CuIIcation has an octahedral coordination environment. It is coordinated by four sulfate O atoms, one of which bridges two CuIIcations, and two O atoms of bridging glycine carboxylate groups. In the crystal structure of (I), the one-dimensional polymers, extending along [001], are linkedviaN—H...O, O—H...O and bifurcated N—H...O,O hydrogen bonds, forming a three-dimensional framework. In the crystal structure of (II), the two-dimensional networks are linkedviabifurcated N—H...O,O hydrogen bonds involving the sulfate O atoms, forming a three-dimensional framework. In the crystal structures of both compounds, there are C—H...O hydrogen bonds present, which reinforce the three-dimensional frameworks.

The crystal structure of the title compound {(C5H14N2)2[Cd2Cl8]} n , (I), consists of hydrogen-bonded 2-methylpiperazinediium (H2MPPA2+) cations in the presence of one-dimensional polymeric {[CdCl3(μ3-Cl)]2−} n anions. The CdII centres are hexacoordinated by three terminal chlorides and three bridging chlorides and have a slightly distorted octahedral CdCl3(μ3-Cl)3 arrangement. The alternating CdCl6 octahedra form four-membered Cd2Cl2 rings by the sharing of neighbouring Cd–Cl edges to give rise to extended one-dimensional ladder-like chains parallel to the b axis, with a Cd...Cd distance of 4.094 (2) Å and a Cd...Cd...Cd angle of 91.264 (8)°. The H2MPPA2+ cations crosslink the [CdCl3(μ3-Cl)] n chains by the formation of two N—H...Cl hydrogen bonds to each chain, giving rise to one-dimensional ladder-like H2MPPA2+–Cl2 hydrogen-bonded chains [graph set R 4 2(14)]. The [CdCl3(μ3-Cl)] n chains are interwoven with the H2MPPA2+–Cl2 hydrogen-bonded chains, giving rise to a three-dimensional supramolecular network.

The molecule of the title compound, C12H9Br2NO2S, is U shaped with the central C—S—N—C segment having a torsion angle of 63.2 (4)°. Further, the dihedral angle between the benzene rings is 38.5 (2)°. The crystal structure features strong N—H...O hydrogen bonds that form infinite [100]C(4) chains. Molecules in adjacent chains are interlinkedviaC—H...O interactions which run along thebaxis, formingC(7) chains. This results in a two-dimensional network in theabplane; adjacent networks are connected by short Br...Br contacts [3.5092 (8) Å] propagating along the diagonal of theacplane, so that a three-dimensional supramolecular architecture ensues.

The syntheses and crystal structures of three molecular salts of protonated 3,4-diaminobenzoic acid, viz. 2-amino-5-carboxyanilinium chloride, C7H9N2O2 +·Cl−, (I), 2-amino-5-carboxyanilinium bromide, C7H9N2O2 +·Br−, (II), and 2-amino-5-carboxyanilinium nitrate monohydrate, C7H9N2O2 +·NO3 −·H2O, (III), are described. The cation is protonated at the meta-N atom (with respect to the carboxy group) in each case. In the crystal of (I), carboxylic acid inversion dimers linked by pairwise O—H...O hydrogen bonds are seen and each N—H group forms a hydrogen bond to a chloride ion to result in (100) undulating layers of chloride ions bridged by the inversion dimers into a three-dimensional network. The extended structure of (II) features O—H...Br, N—H...Br and N—H...O hydrogen bonds: the last of these generates C(7) chains of cations. Overall, the packing in (II) features undulating (100) sheets of bromide ions alternating with the organic cations. Intermolecular interactions in the crystal of (III) include O—H...O, O—H...(O,O), N—H...O, N—H...N and O—H...N links. The cations are linked into (001) sheets, and the nitrate ions and water molecules form undulating chains. Taken together, alternating (001) slabs of organic cations plus anions/water molecules result. Hirshfeld surfaces and fingerprint plots were generated to give further insight into the intermolecular interactions in these structures. The crystal used for the data collection of (II) was twinned by rotation about [100] in reciprocal space in a 0.4896 (15):0.5104 (15) ratio.

In the title compound, C16H14N2O3S, the 1,3-benzoxazole ring system is essentially planar (r.m.s deviation = 0.004 Å) and makes a dihedral angle of 66.16 (17)° with the benzene ring of the methoxyphenyl group. Two intramolecular N—H...O and N—H...N hydrogen bonds occur, forming S(5) and S(7) ring motifs, respectively. In the crystal, pairs of C—H...O hydrogen bonds link the molecules into inversion dimers with R 2 2(14) ring motifs, stacked along the b-axis direction. The inversion dimers are linked by C—H...π and π–π-stacking interactions [centroid-to-centroid distances = 3.631 (2) and 3.631 (2) Å], forming a three-dimensional network. Two-dimensional fingerprint plots associated with the Hirshfeld surface show that the largest contributions to the crystal packing come from H...H (39.3%), C...H/H...C (18.0%), O...H/H...O (15.6) and S...H/H...S (10.2%) interactions.
