Reactions of H2S with AgCl within a porous coordination network

A silver(I) sulfide species is now imbedded in a porous coordination network. Such a composite system builds on the molecule tetrakis(methylthio)-1, 4-benzenedicarboxate that holds out the hard carboxylate to europium(III) to form a host net, while taking on AgCl using its soft sulfur side arms. AgCl is then treated with H₂S to form the dark-colored Ag₂S species, while leaving the hard host net intact and upstanding. This hard-soft duality serves to conjoin the rich electronic flavors of metal chalcogenides and the flexible textures of coordination nets. © 2010 American Chemical Society.
