In the title compound, [Fe(C5H6ClO2)3], the FeIII cation is situated on a twofold rotation axis and is coordinated by six O atoms from three 3-chloropentane-2,4-dionate ligands in a slightly distorted octahedral environment. Fe—O bond lengths are in the range 1.9818 (18)–1.9957 (18) Å. The trans O—Fe—O angles are 169.06 (13) and 171.54 (8)°, whereas the corresponding cis angles are in the range 84.81 (10)–100.68 (12)°. In the crystal, molecules are linked via C—H...Cl interactions.

In the title compound, [Al(C7H9O2)3], the AlIII cation is coordinated by six O atoms from three 2-acetylcyclopentanonate ligands in a slightly distorted octahedral environment, with Al—O bond lengths in the range 1.882 (2)–1.896 (2) Å. In the crystal, molecules are linked together via C—H...O interactions. One of the C atoms in one ring has a large thermal motion compared to the other atoms, indicating some possible disorder. However, the treatment of this C atom as disordered over two positions did not give a significant improvement.

In the title compound, [Zn4(C11H9N2O2)4(C7H5O2)4]·2(CH3)2CO·CH3OH, the tetranuclear molecule lies on a fourfold inversion axis. ZnIIions and μ3-O atoms in the cubane core occupy alternating vertices, forming two interpenetrating tetrahedra. Each ZnIIion is further coordinated by two N atoms from two different (py)2C(OH)O ligands (py is pyridyl) and one O atom from a monodentate benzoate ligand, forming a distorted octahedral environment. The (py)2C(OH)O ligand acts in an η1:η3:η1:μ3manner, forming two five-membered ZnNCCO chelating rings with two different ZnIIatoms sharing a common C—O bond, and an alkoxide-type bond to a third ZnIIion. There are four symmetry-related intramolecular O—H...O hydrogen bonds between the two types of ligands. In the asymmetric unit, there is a half-occupancy acetone solvent molecule and a half-occupancy methanol solvent molecule that lies on a twofold rotation axis.

The ZnIIcenter in the dicationic complex of the title compound, [Zn(C10H7N3S)3](NO3)2·0.5C2H5OH·H2O, is in a distorted octahedral environment with imperfect noncrystallographicC3symmetry. Each 2-(1,3-thiazol-2-yl)-1H-benzimidazole ligand coordinates in a bidentate manner, with the Zn—N(imidazole) bond lengths approximately 0.14 Å shorter than the Zn—N(thiazole) bond lengths. Charge-assisted hydrogen bonds connect cations, anions and water molecules. A lattice void is occupied by an ethanol solvent molecule disordered about a crystallographic inversion center and π-stacking is observed between one type of symmetry-related benzene rings.

The title compound, [Co(C6H6NO3S)2(H2O)2] n , was obtained from a mixture of Co(NO3)2·6H2O and a previously synthesized salt, namely CyNH3·NH2PhSO3, in a 1:1 ratio (Cy = cyclohexyl; Ph = phenyl). The crystal structure consists of a three-dimensional supramolecular framework, in which polymeric layers are interconnected via N—H...O and O—H...O hydrogen bonding. The polymeric layers are formed by an interconnection of neighbouring cobalt(II) cations via NH2PhSO3 − bridges. Each cobalt(II) cation is surrounded by four NH2PhSO3 − moieties and two water molecules, leading to a distorted octahedral environment.

The asymmetric unit of the title compound, [Co(C9H8Cl2NO)3], contains three independent molecules. In each molecule, the CoIIIion is coordinated by an O atom and an N atom from three bidentate 2,4-dichloro-6-(ethyliminomethyl)phenolate ligands in a slightly distorted octahedral environment. In the crystal, a weak C—H...Cl hydrogen bond is observed.

In the title compound, [Mn(C7H5O3)2(C14H12N2)]·C14H12N2·2H2O, the MnII ion is coordinated by a bidentate 2,9-dimethyl-1,10-phenanthroline (dmphen) ligand and two bidentate 3-hydroxybenzoate anions in a distorted octahedral environment. The structure is stabilized by O—H...O and O—H...N hydrogen bonds involving water molecules, the 3-hydroxybenzoate ligands and the uncoordinated dmphen molecules to form a three-dimensional network.

The title compound, [Zn(C12H6O4)(C3H10N2)2] n , has been prepared from zinc(II), naphthalene-2,6-dicarboxylic acid (H2napdc) and 1,3-propylenediamine (pren). The Zn atom lies on a crystallographic centre of symmetry and is coordinated by two monodentate naphthalene-2,6-dicarboxylate ligands and two chelating 1,3-propylenediamine ligands in a distorted octahedral environment. The naphthalene-2,6-dicarboxylate ligands link the Zn atoms, forming a one-dimensional chain structure.

In the crystal structure of the mononuclear title compound, [Mn(NCS)2(C10H8N2)2]·C10H8N2, the MnIIcation is coordinated in an all-cisconfiguration by two N-bound thiocyanate anions and two 2,2′-bipyridine ligands within a slightly distorted octahedral environment. The asymmetric unit consists of one MnIIcation, two thiocyanate anions and two 2,2′-bipyridine ligands, as well as two non-coordinating 2,2′-bipyridine ligands that are each located on centres of inversion. In the crystal structure, the discrete [Mn(NCS)2(C10H8N2)2] complex molecules are arranged in such a way that cavities are formed, in which the solvent 2,2′-bipyridine molecules are located. Apart from van der Waals forces, there are no remarkable intermolecular interactions present in the crystal structure.

The asymmetric unit of the title compound, 3(C13H24N3)+[Bi2I9]3−, comprises two cations and one half of a [Bi2I9]3−ion. The C—N bond lengths of the CN3units in both cations range from 1.336 (3) to 1.364 (5) Å, indicating partial double-bond character pointing towards charge delocalization within the NCN planes. All five-membered rings adopt an envelope conformation with the C atoms as the flap. One of the pyrrolidine rings (cation I) is disordered over two alternative envelope conformations. Two sets of positions were found for two of the methylene groups with an occupancy ratio of 0.757 (10):0.243 (10). The second disordered pyrrolidine moiety (cation II) is disordered around a twofold rotation axis and exhibits two half-occupied symmetry equivalent counterparts. The two BiIIIions are coordinated by six iodide ions in a distorted octahedral manner, with the Bi–I bond lengths ranging from 2.9544 (2) to 3.2414 (2) Å. Two [BiI6]3−octahedra are fused together through face-sharing, forming a dinuclear [Bi2I9]3−unit. The bond lengths of bismuth to the terminal iodides [2.9544 (2)–2.9889 (2) Å] are shorter than the bridging ones [3.1450 (2)–3.2414 (2) Å].
