Abstract
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 ⋯(ΛΛΔΔ) (ΛΛΔΔ)⋯ 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 ⋯(ΛΔ)(ΛΔ)⋯ chiral sequence was obtained.
