catena-Polyzinc-μ3-{33′-(17-dioxa-410-diaza­cyclo­dodecane-410-di­yl)bis­(methyl­ene)dibenzoato}

摘要

The Zn^II ion in the title compound, [Zn(C24H28N2O6)]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-diaza­cyclo­dodecane-4,10-di­yl)bis­(methyl­ene)]dibenzoate anion. It is octahedrally coordinated by two N atoms and two O atoms of the crown moiety from one ligand and two carboxyl­ate 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.
