    The two quinoline rings of the title compound are differently inclined to the plane of the central benzene ring. The intermolecular packing involves C—H···N and π-π stacking interactions.

    X-Ray crystal structures are reported for six transition metal complexes of the ligands 1,2-bis(8-quinolyloxymethyl)benzene (3) and 1,3-bis(8-quinolyloxymethyl)benzene (4). In three mononuclear copper(II) and cobalt(II) complexes ligand 3 acts as a chelating ligand, with either N,O,N’-tridentate or N,O,O’,N’-tetradentate coordination. A novel binuclear silver(I) complex of 3 is shown to be stabilised by a number of weak metal-ligand contacts and multiple intramolecular π−π stacking interactions. In two binuclear copper(II) nitrate complexes of 4, the ligand adopts very different bridging modes of coordination.

    The syntheses and metal complexes of 1,2,4,5-tetrakis(8-quinolyloxymethyl)benzene 1 and hexakis(8-quinolyloxymethyl)benzene 2 are described. X-Ray crystal structures are reported of the free ligand 1, a binuclear silver(i) and a tetranuclear copper(i) complex of 1, as well as a binuclear cobalt(ii) and trinuclear palladium(ii) and silver(i) complexes of 2. Within these discrete metal complexes the ligands are found to adopt a range of coordination modes, with considerable variation in the relative orientations of the ligand arms as a result of the flexibility imparted by the CH₂O linker units.
