Ag~(II)SO4: A Genuine Sulfate of Divalent Silver with Anomalously Strong One-Dimensional Antiferromagnetic Interactions

摘要

The chemistry of coinage metals is rich and surprising, and considerable differences are found between copper, silver, and gold. Among the compounds of Group 11 metals, those of divalent silver are in many ways unique and owe their properties to the remarkable electron-withdrawing power of oxidizing silver(II). As a consequence, many simple binary and ternary connections of divalent silver have not yet been prepared. Particularly intriguing is that a sulfate of silver(II) has not yet been synthesized, given that anhydrous CuSO4 has been meticulously characterized in the past, and the related AuSO4 has been known for a decade.
