摘要：

Two new 4f coordination polymers, [Ln3 center dot(onic)(2)center dot(ox)(4)center dot(H2O)(2)]center dot 4H(2)O(Ln = Yb(1), Tm (2), onic =2-oxynicotinate, ox = oxalate) have been synthesized and characterized by element analysis. IR spectroscopy and thermal analysis, as well as single crystal X-ray diffraction. Complexes 1 and 2 crystallize in the monoclinic system, space group C2/c, which exhibit the network topology with schlafli symbol of (4.6(4).4)(2)(4(2).6(2).8(2)) constructed from Ln(2)(ox) units and onic ligands. Moreover, the two complexes represent the 3D microporous coordination frameworks with 25.7% and 24.1% voids occupied by guest water molecules, respectively. (C) 2012 Elsevier B.V.
