摘要：By control of mixed ligands with particular coordination sites, heterometallic coordination polymers, [Ln(2)(H(2)O)(2)Ag(C(2)O(4))(2)(ina)(3)](n) (Ln = Eu (1), Dy (2), Hina = isonicotinic acid) and {[LnAg(C(2)O(4))(na)(2)]center dot 2H(2)O}(n) (Ln = La (3), Tb (4), Hna = nicotinic acid), have been synthesized under hydrothermal conditions and characterized by elemental analysis, IR, thermogravimetric analysis (TGA), and single-crystal X-ray diffraction. These coordination polymers feature 3D pillar-layered coordination frameworks constructed from two-dimensional (2D) lanthanide-carboxylate layers and Ag(ina) or Ag(na) pillars. It is interesting that the in situ decarboxylation of pyridine-2,3-dicarboxylic acid into nicotinic acid was observed. The luminescent properties of 1 and 4 were also studied.
