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.

In the title complex, [Ni(C12H9N2O3S)2(H2O)2]·4H2O, the NiII ion is coordinated by four N atoms from two bidentate chelating 4-[(pyridin-2-yl)methylideneamino]benzenesulfonate ligands and two O atoms from cis-related water molecules in a slightly distorted octahedral environment [Ni—N = 2.071 (3)–2.121 (3) Å and Ni—O = 2.071 (2) and 2.073 (3) Å]. In the crystal, the coordinated water molecules and the four water molecules of solvation are involved in intermolecular O—H...O hydrogen-bonding interactions with water and sulfonate O-atom acceptors, giving a three-dimensional framework structure.

AbstractA discrete heterotrinuclear complex [{Ni2LDy(OAc)3(CH3OH)}2] · 2CH3OH · 3CH2Cl2, with a naphthalenediol-based acyclic bis(salamo) ligand H4L, has been synthesized and structurally characterized using elemental analyses, IR, UV/Vis and fluorescence spectra and single crystal X-ray diffraction. The crystal structure shows two crystallographically independent but chemically identical molecules (molecules I and II). All the Ni(II) atoms are hexa-coordinated with slightly distorted octahedral geometries. The central Dy atoms are nona-coordinated with slightly distorted tricapped trigonal prism geometries. An infinite 3D supramolecular structure is formed via intermolecular hydrogen bonding and C–H…π interactions.

The crystal structure of the title compound, [Ni(C13H11N2O2)(H2O)4]Br3·2H2O, contains an octahedral NiII atom coordinated to the enol form of 1,3-dipyridylpropane-1,3-dione (dppo) and four water molecules. Both pyridyl rings on the ligand are protonated, forming pyridinium rings and creating an overall ligand charge of +1. The protonated nitrogen-containing rings are involved in hydrogen-bonding interactions with neighoring bromide anions. There are many additional hydrogen-bonding interactions involving coordinated water molecules on the NiII atom, bromide anions and hydration water molecules.

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.

Ethyl-5-methyl-4-imidazolecarboxylate (emizco) is an important intermediate in the synthesis of pharmacological active compounds. In this work, there were synthetized and characterized the following coordination compounds with emizco: <em>trans</em>-[Co(emizco)<sub>2</sub>(H<sub>2</sub>O)<sub>2</sub>](NO<sub>3</sub>)<sub>2</sub> <strong>1</strong>, <em>trans</em>-[Ni(emizco)<sub>2</sub>(H<sub>2</sub>O)<sub>2</sub>](NO<sub>3</sub>)<sub>2</sub> <strong>2</strong>, <em>trans</em>-[Cd(emizco)<sub>2</sub>(H<sub>2</sub>O)<sub>2</sub>](NO<sub>3</sub>)<sub>2</sub> (<strong>3</strong>) and <em>cis</em>-[Cd(emizco)<sub>2</sub>Br<sub>2</sub>] (<strong>4</strong>). 2D or 3D supramolecular arrangements were stabilized. All nitrate <em>trans</em> octahedral compounds stabilized a 3D supramolecular arrangement <em>via</em> hydrogen bonding, throughout the nitrate anions, the ligand and the coordinated water molecules; the <em>cis</em>-octahedral halide complex formed a 2D pleated sheet arrangement, by intermolecular π stacking and halide-hydrogen bonding.

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.
