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(lll) to form a host net, while taking on AgCl using its soft sulfur side arms. AgCI 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. [ABSTRACT FROM AUTHOR]
