Dynamic combinatorial chemistry in a solvothermal process of Cu(I,II) and organosulfur ligands

An unprecedented microwave C(sp(2))-S and S-S bond activation of 2,2'-dipyridyldisul. de (2-dpds) and the formation of a new architecture of coordination networks obtained by reaction of Cu(HCO2)(2)center dot xH(2)O with 2-dpds under solvothermal microwave conditions are reported. This unusual reaction proceeds with the partial oxidation of 2,2'-dipyridyldisul. de to sulfate. The process generates: a Cu(I) dimetallic complex [Cu-2(mu-Hpyt)(2)(Hpyt)(4)](SO4)center dot similar to 5EtOH (1), a Cu(I,II) polycationic coordination polymer [Cu(H2O)(6)][Cu-6(mu-Hpyt)(12)](SO4)(4)center dot 4H(2)O (2) and a dimetallic Cu(II) complex [Cu(2-dps)(mu-SO4)(H2O)](2)center dot 3H(2)O (3). It is worth mentioning the strong red luminescence shown by compounds 1 and 2.
