Stepwise assembly of two 3d-4d heterometallic coordination polymers based on a hexanuclear silver(I) metalloligand

Two novel 3d-4d heterometallic coordination polymers {[Cu-3(bipy)(3)(H2O)(5)][Ag-6(mna)(6)]center dot 11.5H(2)O}(n) (1) and {[Zn-3(eda)(3) (H2O)(4)][Ag-6(mna)(6)]center dot 8H(2)O}(n) (2) were synthesized based on a hexanuclear silver(I) metalloligand by a three-step synthetic method (bipy = 2, 2'-bipyridine, eda = ethylenediamine and H(2)mna = 2-mercaptonicotinic acid). The photoluminescence behaviors of 1 and 2 were also discussed.
