Abstract

The combination of Cu(II) with excess sodium sulfite or a mixture of sodium sulfite and sodium hydrogensulfite produces a colorless solution consistent with the reduction of Cu(II) to Cu(I). The addition of divalent metal ions such as Mn2+, Co2+, Ni2+ and Zn2+ to such solutions, leads to the generation of coordination networks in which the divalent metal ions link together anions of formula Cu(SO3) 47-. This symmetrical anion consists of a tetrahedrally coordinated Cu(I) center bound to the sulfur atoms of four sulfite anionic ligands. Isostructural ID coordination polymers of composition Na 3{[CuI(SO3)4][ZnII(H2O) 2]2}·H2O and Na3{[Cu I(SO3)4][CoII(H2O) 2]2}·H2O, isostructural 2D coordinati..
