The asymmetric unit of the title hydrated salt, C24H35N2O5+·Cl−·2H2O, contains one organic cation that has its protonation site at the amine function, one chloride anion and two lattice water molecules. In the crystal, one pair of lattice water molecules and two chloride anions form a four-membered centrosymmetric hydrogen-bond cycle. In addition, O—H...O, N—H...O and N—H...Cl hydrogen bonds involving the N—H groups, the water molecules and the C=O group are observed. As a result, a hydrogen-bonded layer parallel to (100) is formed. The thickness of such a layer corresponds to the length of theaaxis [21.977 (3) Å].

The asymmetric unit of the title compound, C10H9N2 +·0.5C2O4 2−·C2H2O4·H2O, consists of a 2,2′-bipyridinium cation, half an oxalate dianion, one oxalic acid and one water molecule. One N atom in 2,2′-bipyridine is unprotonated, while the second is protonated and forms an N—H...O hydrogen bond. In the crystal, the anions are connected with surrounding acid molecules and water molecules by strong near-linear O—H...O hydrogen bonds. The water molecules are located between the anions and oxalic acids; their O atoms participate as donors and acceptors, respectively, in O—H...O hydrogen bonds, which form sheets arranged parallel to the ac plane.

The asymmetric unit of the title complex, [Co(NO3)(C10H8N2)(H2O)3]Cl, consists of a chloride anion and a complex cation, which is built on a monodentate nitrate anion, three water molecules and one bidentate 2,2′-bipyridine molecule, coordinated to a CoII cation, in a distorted octahedral geometry. The water molecules are arranged in a facial geometry, and serve as donors for hydrogen bonding. Acceptor sites in the crystal are chloride ions and one O atom of the coordinating nitrate ion. A three-dimensional framework is formed, based on O—H...O and O—H...Cl contacts.

Anion Exchange Reaction

The title hydrated salt, C7H18N3+·OCN−.1.5H2O, was synthesized starting fromN,N,N′,N′,N′′,N′′-hexamethylguanidinium chloride by a twofold anion-exchange reaction. The asymmetric unit contains two cations, two cyanate anions and three water molecules. One cation shows orientational disorder and two sets of N-atom positions were found related by a 60° rotation, with an occupancy ratio of 0.852 (6):0.148 (6). The C—N bond lengths in both guanidinium ions range from 1.329 (2) to 1.358 (10) Å, indicating double-bond character, pointing towards charge delocalization within the NCN planes. Strong O—H...N hydrogen bonds between the crystal water molecules and the cyanate ions and strong O—H...O hydrogen bonds between the water molecules are present, resulting in a two-dimensional hydrogen bonded network running parallel to the (001) plane. The hexamethylguanidinium ions are packed in between the layers built up by water molecules and cyanate ions.

The asymmetric unit of the title compound, C12H13N3O2·H2O, comprises two crystallographically independent organic molecules and two water molecules. There is an O—H...N hydrogen bond between each water molecule and the 2-substituted pyridyl ring of an organic molecule. The water molecules are further engaged in disordered O—H...O hydrogen bonds with each other, leading to the formation of a one-dimensional zigzag chain running parallel to the b axis.

The title compound, {[ZnCl(C13H12F2N6O)2]Cl·2H2O}n, is a two-dimensional coordination polymer. The ZnIIatom is six-coordinated by four N atoms from four 2-(2,4-difluorophenyl)-1,3-bis(1,2,4-triazol-1-yl)propan-2-ol (HFlu) ligands and by two Cl atoms in a distorted octahedral geometry. Two Cl atoms bridge two ZnIIatoms, forming a centrosymmetric dinuclear unit. The HFlu ligands connect the dinuclear units into a 44net parallel to (001) when the dinuclear unit is considered as a node. O—H...O and O—H...Cl hydrogen bonds link the cationic layer, free chloride anions and lattice water molecules. Intralayer π–π interactions between the triazole rings are observed [centroid–centroid distance = 3.716 (6) Å].

In the title compound, C11H10N3OS+·Cl−·2H2O, the organic cation exhibits a dihedral angle of 21.26 (8)° between the mean planes of the pyridine and thiophene rings, and dihedral angles of 15.11 (9) and 6.49 (9)° between the mean planes of the hydrazide moiety and the pyridine and thiophene rings, respectively. In the crystal, the organic cation, the chloride counter-anion and the two water molecules of crystallization are linked through an intricate hydrogen-bonding network consisting of O—H...O, O—H...N, N—H...Cl, C—H...Cl, C—H...O, N—H...O, O—H...Cl and C—H...S interactions that consolidate a three-dimensional network.

In the title hydrated salt, C16H12Cl2N3+·Cl−·H2O, there is a small twist in the cation as seen in the torsion angle linking the benzene ring to the rest of the molecule [171.96 (17)°]. In the crystal, the quinolinium H atom forms a hydrogen bond to the lattice water molecule, which also forms hydrogen bonds to two Cl−anions. Each Cl−ion also accepts a hydrogen bond from the hydrazine H atom. The three-dimensional architecture is also stabilized by π–π interactions between centrosymmetrically related quinoline residues [centroid–centroid distance = 3.5574 (11) Å].
