In the title compound, {[Ag(C6H8N2)(H2O)](C6H4Cl2NO3S)} n , the AgI ion is three-coordinated by two N atoms from two symmetry-related 2,3-dimethylpyrazine (dmp) ligands, and one water O atom in a distorted trigonal–planar geometry. The dmp ligands bridge AgI ions to form a one-dimensional chain structure with charge-balancing 4-amino-2,5-dichlorobenzenesulfonate anions. In the crystal structure, intermolecular O—H...O and N—H...O hydrogen bonds form a two-dimensional network.

In the crystal structure of the title compound, C12H14N4O3, the dihedral angle between the phenyl and imidazole rings is 76.55 (7)°. The nitrite O atoms of the (E)-2-nitriminoimidazolidin-1-yl group act as the acceptors of three N—H...O hydrogen bonds from the N atom of the imidazole ring, resulting in a one-dimensional chain. C—H...O hydrogen-bonding interactions are also observed in this complex, extending the structure into a two-dimensional supramolecular sheet.

In the title compound C19H18NO+·C6H4BrSO3 −, the cation is almost planar. The benzene ring of the anion makes dihedral angles of 84.23 (12) and 84.59 (15)°, respectively, with the quinolinium group and the benzene ring of the cation. The cations and anions are arranged in an alternating one-dimensional chain along the b axis, and these chains are interconnected through C—H...O and C—H...Br interactions to form a three-dimensional network. C—H...π interactions are also observed in the crystal structure.

In the title compound, [Cu(C2H3O2)2(C5H8N2)2], the CuIIatom has a distorted tetragonal–bipyramidal geometry, with the equatorial plane formed by two N atoms belonging to two 3,5-dimethyl-1H-pyrazole ligands and two O atoms from two acetate anions. The second O atoms of the acetate groups provide elongated Cu—O axial contacts, so that the acetates appear to be coordinated in a pseudo-chelate fashion. The pyrazole ligands are situated incispositions with respect to each other. In the crystal structure, molecules are linked through intermolecular N—H...O hydrogen bonds, forming a one-dimensional chain.

In the mononuclear title complex, [Co(N3)2(C12H8N4S)2], the cobalt(II) atom is located on an inversion centre and displays an axially weakly compressed octahedral coordination geometry. The equatorial positions are occupied by the N atoms of two 2,5-bis(pyridin-2-yl)-1,3,4-thiadiazole ligands, whereas the axial positions are occupied by N atoms of the azide anions. The thiadiazole and pyridine rings linked to the metal are almost coplanar, with a maximum deviation from the mean plane of 0.0273 (16) Å. The cohesion of the crystal is ensured by weak C—H...N hydrogen bonds and by π–π interactions between pyridine rings [intercentroid distance = 3.6356 (11) Å], forming a layered arrangement parallel to (001). The structure of the title compound is isotypic with that of the analogous nickel(II) complex [Laachiret al.(2013).Acta Cryst.E69, m351–m352].

The title compound, C23H21N3, comprises a 2-amino-3-cyanopyridine ring fused with a cyclopentane ring. The later adopts an envelope conformation with the central methylene C atom as the flap. The benzyl and andp-tolyl rings are inclined to one another by 56.18 (15)°, and to the pyridine ring by 81.87 (14) and 47.60 (11)°, respectively. In the crystal, molecules are linked by pairs of N—H...Nnitrilehydrogen bonds, forming inversion dimers with anR22(12) ring motif. The dimers are linked by C—H...π and π–π interactions [centroid–centroid distance = 3.7211 (12) Å], forming a three-dimensional framework.
