The cage-like complex, Ag4L4(NO3) 4 (1) [L = 1, 4-bis(pyridine-2-ylmethoxy)benzene] was synthesized by the reaction of the flexible bidentate ligand and silver nitrate. It was characterized by elemental analysis, IR spectroscopy, TG, and single-crystal X-ray analysis. Complex 1 is reported as the first cage-like cluster constructed by four nitrate anions bridging two [2+2] macrocycles. A blue luminescent emission and luminescent enhancement effect are observed in complex 1. Copyright

The synthesis of series of D2h and C2v symmetric oxygenated aromatic dicarboxaldehydes, using dilithiation methodology, is described along with their reactivity in the [3 + 3] cyclocondensation reaction with (1R,2R)-diaminocyclohexane to give oxygenated trianglimine macrocycles. Macrocycles derived from C2v symmetric dialdehydes give macrocycles with a stereogenic aromatic plane with complete diastereocontrol, as a mixture of retainers.
Synthesis and crystal structures of silver(I) and palladium(II) complexes of new bis(2-pyridyloxy)benzenes and methylene extended analogues

Four new ligands, 1,3-bis(2-pyridyloxy)benzene II, 1,2-bis(2-pyridyloxy)benzene III, 1,4-bis(2-pyridyloxymethyl)-benzene IV and 1,4-bis(2-pyridylmethoxy)benzene V, have been prepared, and their complexes with silver(I) nitrate and palladium(II) chloride synthesized. The silver complex of ligand II is shown, by a crystal structure determination, to be a M2L2 20-membered macrocycle with close π-π stacking of the benzene rings of the ligands, similar to the analogous complex of the para substituted isomer of this ligand. The structure of the mononuclear palladium complex of ligand III shows the ligand co-ordinated to the metal in a nine-membered chelate ring, with evidence for a weak interaction between the metal and the central benzene ring. Structures of the silver complexes of ligands IV and V reveal that these are polymeric species, with the molecular packing controlled by π-π stacking interactions between aromatic rings. The crystal structure of the palladium complex of ligand V shows that it self-assembles into a M2L2 26-membered macrocycle, but without intramolecular π-π stacking.
