【 摘 要 】

Depending on the choice of coordinating solvent molecules, the size and nuclearity of metallamacrocycles formed could be controlled. When a manganese ion was assembled with a pentadentate ligand, N-trans- (pentenoyl)salicylhydrazide in amide solvents such as dimethylformamide (DMF) or dimethylacetamide (DMA), an S₆ symmetry puckered dodecanuclear metalladiazamacrocycle with a ···(ニニツツ)(ニニツツ)··· chiral sequence was obtained. However, in an alcoholic solvent such as methanol or ethanol while keeping the other conditions the same, an S8 symmetry octanuclear metalladiazamacrocycle with a ···(ニツ)(ニツ)··· chiral sequence was obtained.
