A team of scientists from Poland have been playing around with silver-pyrazine complexes and made an unusual crystal structure of a Ag(I) by–product in the process. Piotr J. Leszczyński, Wojciech Grochala and colleagues from Warsaw studied the decomposition of di(pyrazine)silver(II) peroxydisulfate under various heat and chemical processes.
Much work has been carried out on the copper analogue before this but only now is the silver version really being looked at. Read more in this recent Hot Article – FREE to read until the end of October:
