In the title compound, [Cu(CH3COO)2(C9H8N2O)2]n, the CuIIion resides on a centre of inversion, displaying a tetragonally distorted octahedral coordination environment defined by two pairs of N and O atoms of symmetry-related 4-(1H-imidazol-1-yl)phenol ligands and the O atoms of two symmetry-related acetate ligands. The bridging mode of the 4-(1H-imidazol-1-yl)phenol ligands is associated with a very long Cu...O interactions involving the phenol O atom of the heterocyclic ligand, which creates chains extending parallel to [100]. In the crystal, the chains are arranged in a distorted hexagonal rod packing and are linkedviaC—H...O hydrogen bonds and by π–π stacking interactions involving centrosymmetrically related pairs of imidazole and phenol rings.

The molecule of the title compound, [NiZnBr2(C17H16N2O2)(C6H7N)2], contains a heterodinuclear arrangement. The two metal ions are bridged via phenol O atoms of the propane-1,3-diylbis(nitrilomethylidyne)]diphenolate (salpd2−) ligand. The two bridging O atoms of salpd2− and two Br atoms constitute a distorted tetrahedral coordination environment around the ZnII ion, while the NiII ion has a distorted octahedral coordination environment formed by two O and two N atoms of salpd2− in the equatorial plane and two N atoms of two 4-methylpyridine ligands in the axial positions. In the crystal structure, weak intermolecular C—H...Br hydrogen bonds link the molecules into chains along the c axis. Weak intramolecular C—H...O and C—H...N hydrogen bonds are also present.

The title compound, [Co(C18H37N2)2(NCS)4], consists of a cobalt(II) ion positioned on the origin of the triclinic unit cell. It is coordinated by the N atoms of two trans-oriented 1-dodecyl-4-aza-1-azoniabicyclo[2.2.2]octane (DABCO+) cations, which carry n-dodecyl chains at the non-coordinating N atoms. The distorted octahedral coordination environment of the CoII ion is completed through four N atoms of isothiocyanate ions, which are arranged within the equatorial plane. Non-classical hydrogen bonding of the types C—H...N and C—H...S between the filamentous molecules lead to the formation of layers parallel to (001).
