AI Article Synopsis
- - Two new cluster-based compounds with a one-dimensional belt-like structure were synthesized using solvothermal methods, featuring mixed-valence antimony (Sb(III,V)) in their compositions.
- - The structures are characterized by anionic clusters arranged in a sandwich formation, involving layers of specific chemical brackets and components related to cobalt and tartaric acid.
- - The second compound was found to have significant proton conductivity, reaching 1.42 × 10⁻² S/cm at 85 °C under high humidity conditions, demonstrating its potential for applications in conductive materials.
Article Abstract
Two isostructural Co(Cd)-antimony-oxo tartrate cluster-based compounds with a one-dimensional (1-D) belt-like structure, namely H[Co(HO)]{(HO){'(HO)[SbO[Co(HO)SbIII6(μ-O)(tta)]]}}·HO ( = Co, ' = Co, = 9 (1); = Cd/Co, ' = Cd/Co, = 7 (2); Htta = tartaric acid), have been synthesized by solvothermal methods. It is noteworthy that the relatively rare mixed-valence Sb(III,V) exists in the structures. The anionic clusters in both compounds appear to be in a sandwich configuration; the top and bottom layers are based on {Sb(μ-O)(tta)} brackets, and the intermediate layer is occupied by {SbO[Co(HO)]}. The title compounds have been characterized by single-crystal X-ray diffraction, powder X-ray diffraction, elemental analyses, thermogravimetric analyses, and UV-Vis spectroscopy. We chose compound 2 as a representative to test its proton conductivity, and the results show that the conductivity can reach 1.42 × 10 S cm at 85 °C under 98% relative humidity.
