| Abstract: | By control of mixed organic ligands with different geometries, three unusual 4d–4f heterometallic coordination polymers, AgLn(nic)2(ox)] · 2H2O Ln = Eu (1); Dy (2); Ho (3)] nic = nicotinate; ox = oxalate] have been synthesized under hydrothermal reaction. Three structures represent 3D open heterometallic coordination frameworks that are constructed from rare zigzag lanthanide-ox-silver chains and nic linkers. Furthermore, the luminescent property of complex 1 was discussed. |
