Abstract: | Hexanuclear 4d–4f heterometallic complexes, Ln2Ag4(ina)8(H2O)10]NO3] 2 · 4H2O Ln = Sm (1), Eu (2), Dy (3) and Hina = isonicotinic acid], have been synthesized by the hydrothermal reaction of lanthanide oxides, AgI, and isonicotinic acid at a suitable temperature. Single-crystal X-ray diffraction studies indicate that these 4d–4f complexes consist of extended 1D zigzag chains structure built upon Sm2Ag4(ina)8(H2O)10] subunits connected by Ag–Ag interactions. Furthermore, the photoluminescent properties of the complex 2 were studied. |
