Abstract

Solvothermal reactions of 5-ethyl-pyridine-2,3-dicarboxylic acid and dipyridyl-type ligands with Zn(Ac)2·2H2O afford three metal–organic frameworks, including {[Zn2(EPDA)2(BPP)2]·(H2O)}n(1), [Zn3(EPDA)2(HEPDA)2(BPE)]n (2) and [Zn3(EPDA)2(HEPDA)2(BPA)]n (3) (H2EPDA = 5-ethyl-pyridine-2,3-dicarboxylic acid, BPP = 1,3-di(4-pyridyl)propane, BPE = 1,2-di(4-pyridyl)ethylene and BPA = 1,2-bi(4-pyridyl)ethane). The pronounced structure for 1 represents a rare 2D → 3D interpenetrated framework with new layer motif featuring a 4-connected net signified as Schläfli symbol of (3.64.8)(32.6.72.8). Complexes 2 and 3 possess intimately related structures featuring infinite Zn carboxylate layers of [Zn3(EPDA)2(HEPDA)2]n pillared by a BPE (or BPA) molecule to produce the three-dimensional frameworks with pcu topology based on the Zn trimers as the 6-connected nodes. It is shown that the flexible degree of dipyridyl-type molecules plays a key role for the assembly of diversified coordination networks. Furthermore, thermal degeneration and fluorescence properties of all three complexes are also investigated.
