Linkage Isomerism in Coordination Polymers Inorganic Chemistry

In chemistry, linkage isomerism or ambidentate isomerism is a form of isomerism in which certain coordination compounds have the same composition but differ in their metal atom's connectivity to a ligand. Typical ligands that give rise to linkage isomers are: • thiocyanate, SCN – isothiocyanate, NCS Nettet10. jan. 2014 · The iodide salt of both nitrito and nitro pentaamminecobalt(III) isomers shows a different DSC curve compared to other salts. As is illustrated in Fig. 1c, the DSC curves of iodide salt of both isomers display two peaks associated with linkage isomerization process.

Nettet20. sep. 2024 · The Fragile X-related disorders (FXDs), which include the intellectual disability fragile X syndrome (FXS), are disorders caused by expansion of a CGG-repeat tract in the 5′ UTR of the X-linked FMR1 gene. These disorders are named for FRAXA, the folate-sensitive fragile site that localizes with the CGG-repeat in individuals with FXS. … NettetDiagnostic fragments confirmed that isomer 1 was fully α-2,3 sialylated, 2 contained α-2,3, as well as α-2,6 linkages and isomer 3 had only α-2,6-linked sialic acids. These findings suggest that sialic acid linkage types are closely related to the elution order since the increase in the number of α-2,6 linkages resulted in higher retention in HILIC mode.

NettetTransition-metal linkage isomers have the same chemical composition, differing only in the nature of the metal–ligand connectivity. 9 For example, when one ammonia in hexaamminecobalt ( III) is substituted by a nitrite anion, nitro, endo -nitrito, and exo -nitrito isomers are formed ( Fig. 1 ). Nettet11. apr. 2024 · In the chemical synthesis of conotoxins with multiple disulfide bonds, the oxidative folding process can result in diverse disulfide bond connectivities, which presents a challenge for determining the natural disulfide bond connectivities and leads to significant structural differences in the synthesized toxins.
