Abstract

The supramolecular silver(I)-thiolate complex [Ag(μ2-SC4N2H4)2(SCN)]n has been prepared from the reaction of AgSCN and pyrimidine-2-thiol in DMF. X-ray diffraction analysis shows that the supramolecular structure exhibits one-dimensional chain through the secondary Ag-S interactions and the chains are further linked by strong hydrogen bonds to form a three dimensional network. The luminescence effect from the silver-centered state of S→Ag LMCT in solid state is different from that in solution due to the secondary Ag-S interactions.
