Diguanidinium bis­(μ-2-hydroxy­propane-1,2,3-tricarboxyl­ato)bis­[diaqua­zincate(II)] dihydrate

The asymmetric unit of the title compound, (CH6N3)2[Zn2(C6H5O7)2(H2O)2]·2H2O, contains one-half of a centrosymmetric dizinc(II) complex anion, one guanidinium cation and one water mol­ecule. Each ZnII ion is hexa­coordinated by two citrate anions, one in a bidentate fashion and the second monodentate, and two water mol­ecules in a distorted octa­hedral geometry. Intra­molecular O—H⋯O hydrogen bonds add further stability to the mol­ecular structure. In the crystal structure, mol­ecules are linked into a three-dimensional framework by inter­molecular N—H⋯O, O—H⋯O and C—H⋯O hydrogen bonds

2,6-Diamino­pyridinium 2-carb­oxy­benzoate

In the crystal of the title mol­ecular salt, C5H8N3 +·C8H5O4 −, the diamino­pyridine cation and the phthalate anion are linked by a pair of N—H⋯O hydrogen bonds. Within the phthalate anion, an almost symmetrical O—H⋯O hydrogen bond is observed. The ion pairs are linked by further N—H⋯O hydrogen bonds, generating a two-dimensional network lying parallel to (10)

Bis(2,6-diamino­pyridinium) tartrate monohydrate

In the title compound, 2C5H8N3 +·C4H4O6 2−·H2O, the two cations are essentially planar [maximum deviations = 0.023 (1) and 0.026 (1) Å]. In one of the cations, the protonated N atom and one of the amino group H atoms are hydrogen bonded to one of the carboxyl groups of the dianion through a pair of N—H⋯O hydrogen bonds, forming an R 2 2(8) ring motif. In the crystal structure, the tartrate anions and water mol­ecules are linked into chains along the c axis by inter­molecular O—H⋯O and C—H⋯O hydrogen bonds. The cations further link the anions and water mol­ecules into a three-dimensional extended structure by a network of N—H⋯O hydrogen bonds. The crystal structure is also stabilized by weak inter­molecular π–π inter­actions [centroid–centroid distance = 3.6950 (6) Å]

Tetra­guanidinium bis­[citrato(3−)]cuprate(II) dihydrate

The asymmetric unit of the title compound, (CH6N3)4[Cu(C6H5O7)2]·2H2O, contains one-half of a centrosymmetric CuII complex anion, two guanidinium cations and a water mol­ecule. The CuII ion, lying on a crystallographic inversion center, is hexa­coordinated with two citrate anions in a distorted octahedral geometry. An intra­molecular O—H⋯O hydrogen bond generates an S(6) ring motif. In the crystal structure, mol­ecules are linked into a three-dimensional framework by inter­molecular N—H⋯O and O—H⋯O hydrogen bonds

Naphthalen-1-aminium chloride

In the crystal structure of the title compound, C10H10N+·Cl−, the two components are connected via N—H⋯Cl hydrogen bonds, forming a layer parallel to the bc plane

Ethyl 4-(phenyl­sulfon­yl)piperazine-1-carboxyl­ate

In the title compound, C13H18N2O4S, the piperazine ring adopts a chair conformation. The dihedral angle between the least-squares planes through the piperazine and benzene rings is 73.23 (10)°. In the crystal, there are no classical hydrogen bonds but stabilization is provided by weak C—H⋯π inter­actions

(2,6-Difluoro­phen­yl)(4-methyl­piperidin-1-yl)methanone

In the title compound, C13H15F2NO, the piperidine ring adopts a chair conformation. The dihedral angle between the least-squares plane of the piperidine ring and the benzene ring is 48.75 (7)°. In the crystal structure, the mol­ecules are connected via C—H⋯O hydrogen bonds, forming a zigzag chain along the b axis

Monoclinic polymorph of poly[aqua(μ4-hydrogen tartrato)sodium]

A monoclinic polymorph of the title compound, [Na(C4H5O6)(H2O)]n, is reported and complements an ortho­rhom­bic form [Kubozono, Hirano, Nagasawa, Maeda & Kashino (1993 ▶). Bull. Chem. Soc. Jpn, 66, 2166–2173]. The asymmetric unit contains a hydrogen tartrate anion, an Na+ cation and a water mol­ecule. The Na+ ion is surrounded by seven O atoms derived from one independent and three symmetry-related hydrogen tartrate anions, and a water mol­ecule, forming a distorted penta­gonal–bipyramidal geometry. Independent units are linked via a pair of inter­molecular bifurcated O—H⋯O acceptor bonds, generating an R 2 1(6) ring motif to form polymeric two-dimensional arrays parallel to the (100) plane. In the crystal packing, the arrays are linked by adjacent ring motifs, together with additional inter­molecular O—H⋯O inter­actions, into a three-dimensional network

Triethyl­ammonium 4-nitro­benzene­sulfonate

In the anion of the title molecular salt, C6H16N+·C6H4O5S−, the nitro group is twisted slightly from the benzene ring, making a dihedral angle of 3.16 (10)°. In the crystal structure, the cations and anions are linked into a two-dimensional network parallel to the ab plane by C—H⋯O and N—H⋯O hydrogen bonds
