摘要: 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, isonicotinic acid at a suitable temperature. Single-crystal X-ray diffraction studies indicate that these complexes consist extended 1D zigzag chains structure built upon [Sm2Ag4(ina)8(H2O)10] subunits connected Ag–Ag interactions. Furthermore, photoluminescent properties complex 2 were studied.
