Two heptanuclear discs, [Co7(L1)6(CH3O)6]2+ (Co7‐L1) and [Co7(L2)12](ClO4)2 (Co7‐L2), have been prepared by the reaction of [Co(H2O)6](ClO4)2 with Schiff base HL1 (HL1=2‐methoxy‐6‐[(methylimino)methyl]phenolate) or benzimidazole derivative HL2 (HL2=(1H‐benzo[d]imidazol‐2‐yl)methanolate), respectively, at room temperature. In contrast, the reaction of [Co(H2O)6](ClO4)2 with a mixture of the two ligands,...
The creek represents a solution reaction system. The crab and the crayfish represent a tridentate Schiff base ligand and a bidentate benzimidazole ligand, respectively. These ligands exhibit a competing trend in the formation of cobalt clusters. Two heptanuclear disks are obtained when a single ligand is employed, following a stepwise assembly: {Co1}→{Co2}→{Co4}→{Co7}. A mixture of the two ligands...
