-piperazine-1,4-diacetato-![[kappa]](/logos/entities/kappa_rmgif.gif)
4N1,O1:N4,O4]Abstract: The asymmetric unit of the title compound, [Zn(C8H12N2O4)(H2O)2]n, contains a ZnII ion residing on an inversion center, half of a centrosymmetric piperazine-1,4-diacetate ligand (L) and a water molecule. The ZnII ion is trans-coordinated by two N,O-bidentate L ligands and by two water molecules in a distorted octahedral geometry. In the crystal structure, intermolecular O-H
O hydrogen bonds link polymeric chains into a three-dimensional supramolecular structure.
