New d10 heterometallic coordination polymers based on compartmental Schiff-base ligands. Synthesis, structure and luminescence

The self-assembly processes between binuclear [Zn2Ln]2+ complex cations and complex anions, [M(CN)2]− [M(I) = Ag(I), Au(I)], generate new one-dimensional (1-D) coordination polymers: 1∞[{L1Zn2(μ3-OH)}2(H2O){μ-[Ag(CN)2]}](ClO4)3 THF 0.5MeOH 1, 1∞[{L1Zn2(μ3-OH)}2(H2O){μ-[Au(CN)2]}](ClO4)3 THF H2O 2, 1∞[{L2Zn2(μ-OH)}{μ-[Ag(CN)2]}][Ag(CN)2] H2O 3 (H2Ln are bicompartmental Schiff-base ligands resulting from condensation reactions between 2,6-diformyl-p-cresol with 2-aminomethyl-pyridine, and 2-aminoethyl-pyridine, respectively). The luminescence properties of the new heterometallic complexes have been investigated.
