In the title complex, [Ni(C12H14N3O3)(C2H3O2)(C5H5N)2], the NiII atom is six-coordinated by two N atoms and one O atom from a tridentate hydrazone ligand, two N atoms from two pyridine molecules, and one O atom from an acetate group, leading to a distorted octahedral geometry. The two N atoms of the pyridine molecules occupy the axial sites and the other four coordinated atoms define the equatorial plane. The uncoordinated acetate O atom forms an intramolecular hydrogen bond with the oxime O atom of the hydrazone ligand.

In the title compound, [Cd(C9H6O5)(C3H4N2)(H2O)2]·3H2O, the carboxylatophenoxyacetate dianion links the water- and imidazole-coordinated Cd atoms into a zigzag chain that runs along the c axis of the monoclinic unit cell; the chelation by the carboxylate arms leads to a seven-coordinate pentagonal–bipyramidal geometry for the Cd atom. The chains are linked into a three-dimensional network by hydrogen bonds.

The VV atom in the title complex, [V(C13H9NO2)(C13H10NO2)O], is coordinated by two O atoms and one N atom of the tridentate Schiff base ligand, and by two O atoms of the bidentate hydroxamate co-ligand, defining a distorted octahedral VO(ONO)(OO) geometry.

In the title centrosymmetric dimeric complex, [V2(C12H13N3O3)2(CH3O)2O2], each VV atom is six-coordinated by one oxo O atom, two N atoms and one O atom of the tridentate hydrazone ligand and two O atoms of two methoxo groups, leading to a distorted octahedral environment. Two VV atoms are bridged by methoxo groups, resulting in a dimer, with a VV separation of 3.324 (3) Å.

In the title coordination polymer, [Zn(C9H6O5)(C8H12N2)]n, the ZnII atom is surrounded by two chelating 3-carboxylatophenoxyacetate (3-CPOA) dianions and one 1,10-phenanthroline (phen) ligand. Adjacent ZnII atoms are bridged by 3-CPOA to form a zigzag chain structure. The polymeric chains are connected via π–π stacking interactions.

In the mononuclear title compound, [La(NO3)3(C5H5NO)2(H2O)2], the LaIII atom is ten-coordinate, with a coordination polyhedron made up of the O atoms of two 4-pyridone ligands, six O atoms of three O,O′-chelating nitrate groups and two water molecules, the polyhedron approximating a dodecahedron. The molecule lies on a twofold rotation axis. A three-dimensional network structure is formed by hydrogen-bonding and π–π stacking interactions.

The crystal structure of the title complex, [Co(C9H7O5)2(C10H8N2)2(H2O)2]·4H2O or [Co(4-CPOAH)2(4,4′-bipy)2(H2O)2]·4H2O (4,4′-bipy is 4,4′-bipyridine and 4-CPOAH− is the 4-carboxyphenoxyacetate monoanion), consists of two independent mononuclear molecules that interact through the uncoordinated water molecules. The CoII atoms lie on inversion centers and display an octahedral geometry defined by two oxyacetate O atoms of 4-CPOAH− groups, two N atoms of 4,4′-bipy ligands and two water molecules. A three-dimensional supramolecular network structure is formed through hydrogen-bonding interactions.

The title compound, (C5H9N2)2(H3O)2[Mo8O26]·2C2H6O, consists of centrosymmetric β-Mo8O264− anions, 3,5-dimethylpyrazolium cations, H3O+ cations and ethanol solvent molecules, linked through hydrogen bonding into a two-dimensional network.

In the title salt adduct, 2H3O+·C10H6O6S22-·2C3H7NO, the 1,5-naphthalenedisulfonate dianion lies on an inversion center. Intermolecular interactions link two hydroxonium cations, one 1,5-naphthalenedisulfonate dianion and two N,N-dimethylformamide molecules into a short hydrogen-bonded chain. A supramolecular hydrogen-bonding network structure is formed via further intermolecular hydrogen bonds.
