Complexes 1–5 are isostructural, exhibiting three-dimensional (3D) heterometallic networks with pcu topology based on the linkages of two-dimensional (2D) lanthanide–oxalate layers and pillar-like M(HPyIDC)2 (M = Fe, Co) subunits. Complexes 6–9 are also isomorphous and display another type of 3D heterometallic coordination framework built through the connections of 2D lanthanide–oxalate layers and one-dimensional (1D) Ag2(PyIDC)2 chains. Interestingly, the oxalate ligands in complexes 6–9 are produced by the in situ decarboxylation of the H3PyIDC ligand in the presence of 4,4′-bipyridine (4,4′-bpy). The photoluminescence, thermal stabilities, and magnetic properties of the selected complexes were also investigated. 2013-08-22T04:49:02Z 2019-12-06T19:44:35Z 2013-08-22T04:49:02Z 2019-12-06T19:44:35Z 2012 2012 Journal Article Cai, S.
