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 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.

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, [MnCl2(C16H20N2O)4]·2C16H20N2O, is composed of two coordinatingN-(adamantan-1-yl)pyridine-4-carboxamide molecules, one Cl−anion, an MnIIion, lying on an inversion centre, and one freeN-(adamantan-1-yl)pyridine-4-carboxamide molecule. The distorted octahedral Mn environment comprises two terminal Cl atoms and four monodentate N atoms from four organic ligands. All the carbamoyl N atoms are involved in intermolecular N—H...O hydrogen-bonding interactions which link the molecules into a chain along theaaxis.

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.

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.

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.
