Abstract

The reaction of 2-pyridylphosphonic acid (LH2) with iron(II) perchlorate and iron(III) nitrate afforded an interconnected, double-layered, cationic iron cage, [{Fe36L44(H2O)(48)}](20+) (1a), the largest interconnected, polynuclear ferric cage reported to date. Magnetic studies on la revealed antiferromagnetic coupling between the spins on adjacent Fe-III ions.

An unprecedented C80 cage that violates the isolated pentagon rule

Pengwei Yu, Mengyang Li, Wangqiang Shen, Shuaifeng Hu, Peng-Yuan Yu, Xinyue Tian, Xiang Zhao, Lipiao Bao, Xing Lu

Summary: Two Lu2O@C-80 isomers, Lu2O@C-1(31876)-C-80 and Lu2O@C-2v(5)-C-80, were successfully isolated and identified using X-ray crystallography. The unprecedented cage structure of C-1(31876)-C-80 with adjacent pentagons can undergo a two-step Stone-Wales transformation to closely connect with C-2v(5)-C-80. The C-1(31876)-C-80 cage plays a crucial role in the transformation map of oxide cluster fullerenes, filling a gap in the formation process.

Heteroleptic Ligation by an endo-Functionalized Cage

Sarah C. Bete, Matthias Otte

Summary: A conceptual approach for the synthesis of quasi-heteroleptic complexes with properly endo-functionalized cages as ligands is introduced. The synthesized cage ligand, inspired by enzymatic active sites, has a covalent organic nature and demonstrates unique coordination properties to transition metals. Analysis of the iron(II) complex in both solution and solid state confirms the structure and lack of undesired dimerization, making Fe@2 a detailed structural model complex for non-heme iron oxygenases.

Actinorhodin Biosynthesis Terminates with an Unprecedented Biaryl Coupling Reaction

Makoto Hashimoto, Susumu Watari, Takaaki Taguchi, Kazuki Ishikawa, Takuya Kumamoto, Susumu Okamoto, Koji Ichinose

Summary: In this study, we identified two enzymes, ActVA-ORF4 and ActVA-ORF3, involved in the last step of ACT biosynthesis. ActVA-ORF4 catalyzes the intermolecular C-C bond formation using DHK-OH as the substrate, while ActVA-ORF3 is a quinone-forming enzyme that produces the coupling substrate DHK-OH and the final product ACT.

Unprecedented Wavelength Dependence of an Antimony Chalcohalide Photovoltaic Device

Ryosuke Nishikubo, Shaoxian Li, Akinori Saeki

Summary: This paper reports an unprecedented wavelength-dependent photovoltaic effect in antimony chalcoiodide and antimony chalcoiodide-antimony sulfide devices, where the open-circuit voltage can be rapidly and reversibly changed by changing the irradiation wavelength. This effect allows for a wavelength-recognizable single-junction photodetector and provides deep insights into photovoltaic physics.

Summary: This study reports the structure and function of the cyanobacterial enzyme CylK, revealing its active site and key catalytic amino acid residues. Analysis of CylK homologs suggests conservation of these residues with potential divergent reactivity and altered secondary metabolism. By studying this unusual biosynthetic transformation, this work fills a gap in our understanding of how enzymes activate and use alkyl halides as biosynthetic intermediates.

Controllable chiral memory in an anion tetrahedral cage

Wenyao Zhang, Jie Zhao, Dong Yang, Boyang Li, Yang Feng, Yue Wang, Xiaoyan Zheng, Xiao-Juan Yang, Biao Wu

Summary: This study presents the chiral induction and memory effect in an anion-coordination-driven tetrahedral cage. The induced chirality can be retained for a certain period even after replacing the chiral guests with achiral ones. The retention time of induced chirality can be controlled by using different achiral guests.

Chirality Gearing in an Achiral Cage through Adaptive Binding

Qi-Ping Hu, Hao Zhou, Teng-Yu Huang, Yu-Fei Ao, De-Xian Wang, Qi-Qiang Wang

Summary: An adaptive, achiral trithiourea molecular cage and its conformational and stereodynamics toward tricarboxylate anion binding are reported. The cage exhibits a flexible conformation and strongly binds 1,3,5-benzene tricarboxylate, forming a sandwich-like inclusion complex. By incorporating chiral arms on the guest, a gear-like complex with a specific helical sense is produced.

Molecular and Electronic Structures and Single-Molecule Magnet Behavior of Tris(thioether)-Iron Complexes Containing Redox-Active α-Diimine Ligands

Peng Wang, Mohamed R. Saber, Peter E. VanNatta, Glenn P. A. Yap, Codrina Popescu, Christopher C. Scarborough, Matthew T. Kieber-Emmons, Kim R. Dunbar, Charles G. Riordan

Summary: Incorporating radical ligands into metal complexes is a growing trend in the design of single-molecule magnets. The described mononuclear transition metal SMMs feature high-spin iron(II) complexes with antiferromagnetically coupled alpha-diiminato radical ligands. Experimental and theoretical studies indicate that these complexes exhibit slow magnetic relaxation behavior with a strong magnetic exchange coupling.

Summary: New axially blocked unsymmetrical dirhodium complexes can photocatalyze the production of H-2 under red light irradiation with a high turnover number (TON) of 23 +/- 3 in the presence of acid and a sacrificial donor, thanks to their multiple metal/ligand-to-ligand charge transfer transitions that improve their absorption of light into the near-IR.
