摘要

Two 2D 4d-4f heterometallic coordination polymers, [LnAg- (Py26DC)_2(H_2O)_3]·3H_2O [Ln = Nd (1), La (2); H_2Py26DC = pyridine- 2,6-dicarboxylic acid], and one 2D lanthanide homometallic coordination polymer, [Ln(Py25DC)(ox)_(0.5)(H_2O)_2] [Ln = Tm (3); H_2Py25DC = pyridine-2,5-dicarboxylic acid; ox = oxalate], were synthesized and characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis, and single-crystal X-ray diffraction analysis. Both complexes 1 and 2 are isostructural and exhibit 3-connected 2D heterometallic layer structures with the Schl?fli symbol of (8~2·10), whereas complex 3 represents an extended 2D homometallic network structure with (4,4) topology.
