In the title complex, [Ni(C9H4N2O4)(C12H8N2)(H2O)2]n, the NiIIatom is hexacoordinated by one N and one O atom from two different 1H-benzimidazole-5,6-dicarboxylate ligands, two N atoms from one 1,10-phenanthroline ligand and two water molecules. The flexible 1H-benzimidazole-5,6-dicarboxylate ligands link the NiIIcentres, forming an infinite zigzag chain parallel to [001]. The crystal packing is governed by intermolecular hydrogen-bonding interactions of the O—H...O, N—H...O and C—H...O types.

In the title disodium salt, 2Na+·C14H12N2O6S2 2−·4H2O, the two aryl units of the centrosymmetric anion are coplanar. The E geometric isomer was exclusively found, while the mean plane of the unsaturated group is twisted by 10.1 (2)° from the mean plane described by the two aminobenzenes. Four water molecules cocrystallize and participate in intermolecular hydrogen bonding. The anions lie in parallel planes separated by 3.367 (16) Å and their symmetry-related benzene rings are separated by 3.84 (1) Å, leading to weak intermolecular π-stacking.

The structure of tetraaqua[2,6-diacetylpyridine bis(semicarbazone)]samarium(III) trinitrate, [Sm(C11H15N7O2)(H2O)4](NO3)3, has monoclinic (P21/c) symmetry. The 2,6-diacetylpyridine (DAPSC) ligand is pentadentate. The coordination of the DAPSC ligand and four coordinated water molecules around the metal cation is best described as a distorted tricapped trigonal prism. The structure displays intermolecular hydrogen bonding. The structure is isomorphous with many other published lanthanide(III) nitrate salts with the DAPSC ligand, 2,6-diacetylpyridinebis(semicarbazone). One of the three nitrate counter-anions is disordered, which is consistent with the structures of other +3 lanthanide nitrate salts with DAPSC. Refinement of occupancies for the disordered nitrate group gave major and minor occupancies of 54.9 (14) and 45.1 (14)%, respectively.

The crystal structures of three quinuclidine-based compounds, namely (1-azabicyclo[2.2.2]octan-3-ylidene)hydrazine monohydrate, C7H13N3·H2O (1), 1,2-bis(1-azabicyclo[2.2.2]octan-3-ylidene)hydrazine, C14H22N4 (2), and 1,2-bis(1-azoniabicyclo[2.2.2]octan-3-ylidene)hydrazine dichloride, C14H24N4 2+·2Cl− (3), are reported. In the crystal structure of 1, the quinuclidine-substituted hydrazine and water molecules are linked through N—H...O and O—H...N hydrogen bonds, forming a two-dimensional array. The compound crystallizes in the centrosymmetric space group P21/c. Compound 2 was refined in the space group Pccn and exhibits no hydrogen bonding. However, its hydrochloride form 3 crystallizes in the noncentrosymmetric space group Pc. It shows a three-dimensional network structure via intermolecular hydrogen bonding (N—H...C and N/C—H...Cl). Compound 3, with its acentric structure, shows strong second harmonic activity.

AbstractThe synthesis and structural characterization of N-(6-methoxypyridin-3-yl)-4-(pyridin-2-yl)thiazol-2-amine mono-hydrobromide monohydrate (3) and N-(6-methoxypyridin-3-yl)-4-(pyrazin-2-yl)thiazol-2-amine mono-hydrobromide 0.35 methanol solvate (4) are reported. The crystal structures of 3 (monoclinic, space group P21/n, Z = 4) and 4 (monoclinic, space group, C2/c, Z = 8) feature N,4-diheteroaryl 2-aminothiazoles showing similar molecular conformations but different sites of protonation and thus distinctly different intermolecular hydrogen bonding patterns. In 3, Namine–H⋯Br−, N+pyridine–H⋯Owater, and Owater–H⋯Br− hydrogen bonds link protonated N-(6-methoxypyridin-3-yl)-4-(pyridin-2-yl)thiazol-2-amine and water molecules and bromide anions into a three-dimensional hydrogen-bonded network, whereas intermolecular N+methoxypyridine–H⋯Npyrazine hydrogen bonds result in hydrogen-bonded zigzag chains of protonated N-(6-methoxypyridin-3-yl)-4-(pyrazin-2-yl)thiazol-2-amine molecules in 4.
