Abstract |
Two O3S2-macrocycles with different S…S distances (L1 < L2) were employed as a strategy to isolate the adaptive products including dicopper(II) complex via controlling exo-coordination modes. L1 gave a one-dimensional coordination polymer [Cu2(L1)2(NO3)4]n (1) based on a convergent exo-coordination. Meanwhile, L2 resulted in the formation of a divergent exo-coordinated dicopper(II) complex [Cu2(L2ox)4(μ-Cl)](NO3)4 (2), in which four oxidized macrocycles (L2ox) act as paddles and CuII-(μ-Cl)-CuII entity as an axis shaft adopting a four-paddled watermill. The chloro-bridging ligand (μ-Cl) in 2 is derived from the dichloromethane solvent and stabilized by C-H…Cl- H-bonding. The overall watermill structure is also stabilized by interligand C-H…O H-bonding to form a pseudo-cage. The present result demonstrates that a combination of the controlled exo-coordination and the induced species serve a consistent picture of the adaptive formation of a new type dicopper(II) complex with a highly organized structure. |
