Abstract:
In the title coordination polymer, [Zr(C8H2O6)(C5H10N2O)2] n , the Zr(IV) atom (site symmetry 2) is coordinated by two O,O'-bidentate 2,5-dioxidoterephthalate (DHTP(4-)) ligands and two O-bonded 1,3-dimethyl-2-imidazolidinone (DMI) ligands (the latter in a cis orientation) in a distorted ZrO6 octa-hedral geometry. The deprotonated hy-droxy and carb-oxy O atoms of the DHTP(4-) ligand chelate the Zr(IV) ion via a six-membered ring; the dihedral angle between the carboxyl-ate group and the aromatic ring is 14.46 (11)°. The DHTP(4-) ligand is completed by crystallographic inversion symmetry and coordinates to two Zr(IV) atoms, thereby forming polymeric zigzag chains propagating in [001].
