Synthesis and Crystal Structure of a Zinc Coordination Polymer Based on Bis(4-(2'-methylimidazol)phenyl)sulfone and (1,1'-Biphenyl)-2,2'-dicarboxylate Ligands

Zinc coordination polymer with V-shaped ligands, {[Zn(L¹) ⋅ (bpda)] ⋅ H₂O}_n, (1) (L¹ = bis(4-(2'-methylimidazol)phenyl)sulfone, H₂bpda = (1,1'-biphenyl)-2,2'-dicarboxylic acid) was synthesized under solvothermal condition. The structure of 1 was determined by single-crystal X-ray diffraction analysis and further characterized by infrared spectra and elemental analyses. In 1, the Zn(II) ion is four-coordinated by two nitrogen atoms of two distinct L¹ ligands and two oxygen atoms of two bpda^2– to form a distorted tetrahedron. Complex 1 displays a 2D four-connected framework with a (6⁵ × 8) topology along c direction.
