Keywords: X-ray diffraction / Silver / Supramolecular chemistry / S ligands / Bridging ligands + cation and all four oxygen atoms of each ClO 4 − anion involved in N−H···O−Cl hydrogen bonding associations. This leads to the assembly of a three-dimensional supramolecular network. Complex 2, whose previously reported structure has been redetermined with higher precision, contains catena-[Ag(py2tH) 2 ] n n+ polymeric cations consisting of linear chains
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
