摘要

我们分离出了通式为[L4Ni16(RCOO)16(H2O)x(MeOH)12-x]（其中 H4L = 1,4-双((E)-((2'-羟基苄基)亚氨基)甲基)-2,3-萘二醇，R = H 或 Me）的四种新的 Ni16 分子轮。络合物 C1 - C3（R = Me）是用醋酸镍（II）形成的，并以多晶体形式出现，其带电成分的配方相同。在使用甲酸镍（II）制备的 C4（R = H）中也观察到了相同的轮状结构，这表明该系统具有进一步多功能化的潜力。与类似的四倍对称镍（II）轮簇相比，C1 的静磁特性测量结果表明，存在主要的反铁磁相互作用和 S = 0 基态。

Self-Assembly of four Ni₁₆ Molecular Wheels with Capsule and Tubular Supramolecular Architectures.

Four new Ni₁₆ molecular wheels with the general formula [L₄Ni₁₆(RCOO)₁₆(H₂O)_x(MeOH)_12-x] (where H₄L=1,4-bis((E)-((2'-hydroxybenzyl)imino)methyl)-2,3-naphthalenediol, and R=H or Me) have been isolated and structurally characterised. Complexes C1-C3 (R=Me) were formed using nickel (II) acetate and presented as polymorphs with the same formulation of charged components. The same wheel-like architecture was observed in C4 (R=H), which was prepared using nickel (II) formate, demonstrating the potential for further versatility of the system. In contrast to similar four-fold symmetric Ni(II) wheel clusters, measurements of the static magnetic properties of C1 indicated the presence of dominant antiferromagnetic interactions and an S=0 ground state.

期刊介绍： Chemistry—An Asian Journal is an international high-impact journal for chemistry in its broadest sense. The journal covers all aspects of chemistry from biochemistry through organic and inorganic chemistry to physical chemistry, including interdisciplinary topics. Chemistry—An Asian Journal publishes Full Papers, Communications, and Focus Reviews. A professional editorial team headed by Dr. Theresa Kueckmann and an Editorial Board (headed by Professor Susumu Kitagawa) ensure the highest quality of the peer-review process, the contents and the production of the journal. Chemistry—An Asian Journal is published on behalf of the Asian Chemical Editorial Society (ACES), an association of numerous Asian chemical societies, and supported by the Gesellschaft Deutscher Chemiker (GDCh, German Chemical Society), ChemPubSoc Europe, and the Federation of Asian Chemical Societies (FACS).
