Formula: C5H6BNO2 And the article was included in Materials Science & Engineering, B: Advanced Functional Solid-State Materials in 2020. The article conveys some information:
A series of new hybrid iodometallates [H4Spiro-4-py]n[Cu7I10]n(I3-)n·0.5(I2)n·nH2O (1), [Cu2I2(Spiro-3-py)]n·0.75n(DMF)·0.25nH2O (2), [H2Spiro-4-py][H3Spiro-4-py][Ag10I20]0.5·H2O (3) and [H2Spiro-4-py]n[H3Spiro-4-py]n[Ag8I13]n·2.5H2O (4) were hydrothermal synthesized. 1 Contains 1-D chain [Cu7I10]n based on new [Cu7I12] cluster, free I3- anions and I2 mols., which are interconnected by weak I···I interactions to generate a novel polyiodide {[Cu7I10](I3-)·(I2)}n framework. 2 Features a neutral sql layer [Cu2I2(Spiro-3-py)]n constructed by the interconnection of the {Cu2I2} dimers and Spiro-3-py ligands. The anionic [Ag10I20]10- framework of 3 can be described as an aggregation of two tetrameric [Ag4I8] clusters and one dimeric [Ag2I6] unit via sharing corner. The 1-D anionic chain [Ag8I5-13]n of 4 is built up from the alternate connection of tetrameric [Ag4I8] units and rare larger [Ag12I20] clusters, which offers the only example of 1-D iodoargentates based on two types of iodoargentate clusters. The optical and photoelectronic properties of all compounds were also studied. In the experiment, the researchers used Pyridin-3-ylboronic acid(cas: 1692-25-7Formula: C5H6BNO2)
Pyridin-3-ylboronic acid(cas: 1692-25-7) belongs to pyridine. Pyridines form stable salts with strong acids. Pyridine itself is often used to neutralize acid formed in a reaction and as a basic solvent. Formula: C5H6BNO2
