catena-Poly[[[bis-(methyl-amine)zinc(II)]-μ-4,4'-oxydibenzoato] N,N-dimethyl-acetamide solvate].

In the title zinc(II) coordination polymer, {[Zn(C(14)H(8)O(5))(CH(5)N)(2)]·C(4)H(9)NO}(n), each Zn(II) cation is tetra-hedrally coordinated by two carboxyl-ato O atoms of two oba anions (H(2)oba 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.
