The title complex, [Co(C10H6NO2)2(CH4O)2], is a neutral mononuclear complex containing a CoII ion in a six-coordinate environment. The CoII center, located on a crystallographic center of symmetry, displays a slightly distorted octa­hedral geometry, with two quinoline-8-carboxyl­ate and two methanol ligands in trans configurations. The complex mol­ecules are linked together by O—H...O and C—H...O hydrogen bonds between methanol mol­ecules and carboxyl­ate groups to form a three-dimensional framework.

In the structure of the title complex, [Cu(N3)2(C14H15N3O2)]·H2O, the Cu atom exhibits a CuN5O coordination environment formed by five N atoms, three from the N,N-bis­(2-pyridymeth­yl)glycine (bpg) ligand and two from azide anions, and one O atom belonging to bpg. The Cu—N distances range from 1.931 (3) to 1.960 (3) Å, with an average of 1.945 (3) Å, and the Cu—O distance is 1.900 (2) Å. The azide ligands are almost linear, with both N—N—N angles being 174.7 (4)°.

The title complex, [Cu2(C16H10NO2)4(H2O)2], has a centrosymmetric wheel-shaped dinuclear structure in which two symmetry-related CuII centers are bridged by four carboxyl­ate groups of distinct 2-phenylquinoline-4-carboxyl­ate (phqc) ligands, the Cu—Cu separation being 2.6507 (12) Å. Each CuII center is five-coordinated by four O atoms of carboxyl­ate groups in the basal plane and one O atom of a water mol­ecule in the apical position. In addition, the dinuclear mol­ecules are linked by inter­molecular O—H...N hydrogen bonds to form a one-dimensional supramolecular chain.

The title complex, [HgBr2L] [L is 1,4-bis­(ethyl­sulfanyl)butane, C4H9S], has a dinuclear structure in which one L ligand links two HgBr2 units. A C2 symmetry axis passes through the centre of the ligand L. The HgII centre adopts a slightly distorted trigonal planar geometry coordinated by two Br anions and one S atom from L. When two weak Hg—Br interactions are considered, the dinuclear structure expands into a two-dimensional layer containing [HgBr2]n chains, with the HgII ion having a trigonal–bipyramidal geometry and the Br anion acting as a μ2 linkage.

The title complex, [Hg2Br4(C18H22S2)]n, has a chain structure. Two bridging Br atoms and two terminal Br atoms coordinate to two HgII atoms to form a (HgBr2)2 dimer, and the 1,4-bis­(benzyl­sulfan­yl)butane ligands bridge the (HgBr2)2 dimers to form a one-dimensional chain. The dimer and butane ligand are each located on inversion centers. HgII adopts a tetra­hedral geometry formed by three Br and one S atoms.
