A novel luminescent 3D metal–organic framework possessing 4-fold interpenetrating (3,4)-connected net

A novel 3D polymer [Zn(L1)(1,4-BDC)0.5] (1) (HL1 = 3,5-bis(pyridin-4-ylmethoxy)benzoic acid, 1,4-BDC = 1,4-benzenedicarboxylate anion) has been isolated under hydrothermal condition and characterized by single crystal X-ray diffraction. Compound 1 displays a 3D 4-fold interpenetrating (3,4)-connected net with (4 · 82)(4 · 85) topology. In addition, powder X-ray diffraction, photoluminescent property and thermogravimetric analysis for 1 are investigated in detail.
