Synthesis, Structure, and Luminescence of a Zinc Coordination Polymer Based on Bis(4-(2'-methylimidazol)phenyl)sulfone and 4-Nitrophthalate Ligands

Аннотация

A zinc coordination polymer with V-shaped ligands, [L¹Zn(npa)]_n (L¹ = bis(4-(2'-methylimidazol)phenyl)sulfone, H₂npa = 4-nitrophthalic acid) has been synthesized under solvothermal conditions. The structure has been determined by single-crystal X-ray diffraction analysis and characterized by IR spectra, and elemental analyses. In crystal adjacent [Zn₂(npa)₂] units linked by four bridging ligands L¹ form 2D layers, which are entangled between each other giving inclined interpenetration with the angle of 52.9°, thus resulting in a complicated 3D unique network. Moreover, luminescent properties of the title compound have been investigated.
