Abstract

Nine 3D heterometallic coordination polymers, namely [NaLn2Cu6I5(IN)6(ox)(H2O)4]·H2O [Ln = La (1), Eu (2), Gd (3), Tb (4), HIN = isonicotinic acid, ox = oxalate], [Ln2Ag4(IN)5(ox)2(NO3)(H2O)2]·3H2O [Ln = Dy (5), (6) Ho], [LnAg(IN)2(ox)]·H2O [Ln = La (7), Pr (8), Tm (9)] have been successfully synthesized under hydrothermal conditions. Compounds 1–4 exhibit same unusual 3D pillared-layer heterometallic coordination frameworks that are built up by the Ln-ox-Na layers, 2D inorganic [(Cu6I5)+]n layers and IN ligands. Compounds 5 and 6 represent 3D coordination frameworks that are constructed from rare Ln(III)-ox-IN chains and Ag(I)-IN-ox layers. 3D coordination networks of compounds 7–9 are built up from 2D Ln(III)-IN-ox layers and Ag(I)-IN-ox subunits. Furthermore, the magnetic properties of compounds 5 and 6 and the luminescence properties of compounds 2, 4 and 5 have been investigated.
