A two-dimensional network: poly[aqua-₂-1,4-diazabicyclo[2.2.2]octane-₂-terephthalato-zinc(II)]

Abstract: In the title complex, [Zn(tp)(dbo)(H₂O)]_n, where tp is terephthalate (C₈H₄O₄) and dbo is 1,4-diazabicyclo[2.2.2]octane (C₆H₁₂N₂), each Zn^II atom is coordinated by three O atoms from two bis-monodentate tp ligands and one aqua ligand, and by two N atoms from two bridging dbo ligands, in a distorted trigonal-bipyramidal geometry, with the two N atoms located at the axial sites. The bridging tp ligands link the Zn^II atoms to form one-dimensional zigzag chains, running along [221]. These chains are assembled into layers parallel to the ac plane by dbo ligands, which are extended into a three-dimensional network by O-HO hydrogen bonds and - stacking interactions.
