چکیده
The Zn(II) ion in the title compound, [Zn(C(24)H(28)N(2)O(6))](n), is located on a twofold rotation axis and is at the midpoint of a crown-4 moiety of 3,3'-[(1,7-dioxa-4,10-diaza-cyclo-dodecane-4,10-di-yl)bis-(methyl-ene)]dibenzoate anion. It is octahedrally coordinated by two N atoms and two O atoms of the crown moiety from one ligand and two carboxyl-ate O atoms from two bridging intra-chain ligands. Metallomacrocyclic rings are identified in the structure. The metallomacrocycle contains two Zn(II) ions and 14 atoms from the bridging ligands. Repetition of these units gives rise to an infinite zigzag chain along [101]. C-H⋯O hydrogen bonds occur.
