Catena-Poly[[[bis-(methyl-amine)zinc(II)] -μ- 4,4′-oxydibenzoato] N,N-dimethyl-acetamide solvate]

In the title zinc(II) coordination polymer, {[Zn(C14H8O5)(CH5N)2] ·C4H9NO} n , each Zn(II) cation is tetra-hedrally coordinated by two carboxyl-ato O atoms of two oba anions (H2oba is 4,4′-oxydibenzoic acid), and two N atoms from two methyl-amine mol-ecules. Each oba anion bridges two Zn(II) cations through the two carboxyl-ate groups in a monodentate fashion, forming one-dimensional polymeric chains. These chains are linked via N-H⋯O hydrogen bonds, forming a two-dimensional supra-molecular network.
