Hexanuclear 4d-4f complexes [Ln2Ag4(ina)8(H2O)10][NO3]2 · 4H2O (Ln = Sm, Eu, Dy): Syntheses, structures and photoluminescent properties

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. These 4d-4f complexes consist of extended 1D zigzag chains structure built upon [Sm2Ag4(ina)8(H2O)10] subunits connected by Ag-Ag interactions.
