Abstract

A Zn(II) based two-dimensional (2D) metal-organic framework (MOF) [Zn3(cis,trans-muco)3(4,4′-bpy)3]·4H2O (1) has been synthesized by slow diffusion method using cis,cis-muconic acid (H2cis,cis-muco) and 4,4′-bipyridine (4,4′-bpy) mixed ligands. The synthesized compound 1 has been structurally characterized by single crystal X-ray diffraction (SCXRD), powder X-ray diffraction (PXRD) techniques, and thermogravimetric analysis (TGA). The solid-state structure of 1 reveals in situ cis,cis- to cis, trans- isomerization of muconate ligand under visible light, which predominately coordinates to Zn(II). The compound 1 comprises binuclear Zn2 secondary building units (SBUs) which propagate in ab plane to furnish 2D framework with (4,4) net topology. Interestingly, compound 1 shows photoluminescence property and can be used as luminescent probe. The non-covalent interactions within the compound 1 have been investigated by means of Hirshfeld surface analysis.
