In the title compound, [Cd(C2H8N2)3](GeF6), the CdIIatom, lying on a 32 symmetry site, is coordinated by six N atoms from three ethylenediamine (en) ligands in a distorted octahedral geometry. The Ge atom also lies on a 32 symmetry site and is coordinated by six F atoms. The en ligand has a twofold rotation axis passing through the mid-point of the C—C bond. The F atom is disordered over two sites with equal occupancy factors. In the crystal, the [Cd(en)3]2+cations and [GeF6]2−anions are connected through N—H...F hydrogen bonds, forming a three-dimensional supramolecular network.

In the title polymeric complex, {[Fe(C12H10N2)2(H2O)4](CH3C6H4SO3)2·2CH3OH}n, the FeIIcation, located on an inversion centre, is coordinated by four water molecules in the equatorial positions and two 1,2-bis(pyridin-4-yl)ethene molecules in the axial positions. This results in a distorted octahedral geometry for the [N2O4] coordination polyhedron. The 1,2-bis(pyridin-4-yl)ethene molecules bridge the FeIIcations, forming polymeric chains running along thea-axis direction. Stabilization of the crystal structure is provided by O—H...O hydrogen bonds; these are formed by coordinated water molecules as donors towards the O atoms of the methanol molecules and tosylate anions as acceptors of protons, leading to the formation of a three-dimensional supramolecular network. Weak C—H...O hydrogen bonds are also observed in the crystal.

There are three independent CdII ions in the title complex, {[Cd3(C10H3O8)2(H2O)4]·4H2O} n , one of which is coordinated by four O atoms from three 5-carboxybenzene-1,2,4-tricarboxylate ligands and by two water molecules in a distorted octahedral geometry. The second CdII ion is coordinated by five O atoms from four 5-carboxybenzene-1,2,4-tricarboxylate ligands and by one water molecule also in a distorted octahedral geometry while the third CdII ion is coordinated by five O atoms from three 5-carboxybenzene-1,2,4-tricarboxylate ligands and by one water molecule in a highly distorted octahedral geometry. The 5-carboxybenzene-1,2,4-tricarboxylate ligands bridge the CdII ions, resulting in the formation of a three-dimensional structure. Intra- and intermolecular O—H...O hydrogen bonds are present throughout the three-dimensional structure.

The structure of the title compound, [Co2(C7H7N2O2)4(H2O)2]·2H2O, consists of a centrosymmetric binuclear [Co2(4-Apha)4(H2O)2] complex molecule (4-AphaH = 4-aminophenylhydroxamic acid), and two solvent water molecules. Each CoII cation is six coordinate, binding five oxygen atoms from three 4-Apha− ligands and a water molecule in a slightly distorted octahedral geometry. Two of the 4-Apha− ligands bridge two neighbouring CoII ions to form the binuclear complex. A three-dimensional network structure is generated by O—H...O, N—H...O, and N—H...N hydrogen bonds.
