“…Interestingly, the combination of d 10 metal carboxylates and pyridine derivatives has already led to the formation of excellent luminophores. 12 Our group has previously studied the coordination chemistry of d 10 metal ions towards carboxylic acids holding ether groups, 13,14 observing that Hg(II) and Hg(I) have a preferential interaction over Zn(II) and Cd(II) with these O atoms, leading to the arrangement of unusual structures. Instead, in the presence of Zn(II) and Cd(II), the dioxole O atoms did not participate in the coordination environment and only promoted weak C-H⋯O interactions.…”
