摘要: The hydrothermal reaction of rare earth nitrates, CuCN, 1H-1,2,3-triazole-4,5-dicarboxylic acid (H3tda), and isonicotinic (Hina) resulted in the formation a new series 3d–4f heterometallic coordination polymers [LnCu(tda)(ina)2(H2O)]·3H2O (Ln = Eu (1), Tb (2), Gd (3), Dy (4), Ho (5)], H3tda acid, Hina acid). Complexes 1–5 are isostructural structurally characterized by elemental analysis, FT-IR spectroscopy, thermogravimetric analysis (TGA), single-crystal powder X-ray diffraction (PXRD). Single-crystal reveals that metal cations these compounds firstly interconnected ligands to produce carpet-shaped ring [Ln2(tda)2Cu4], then pillared bridging molecules form 3D layer-pillared porous Ln(III)–Cu(II) polymers. In addition, magnetic properties were also investigated detail.
