Poly[bis­(N,N-dimethyl­acetamide)-1κO,2κO-bis­(μ(4)-thio­phene-2,5-di­car­boxyl­ato-1:2:1′:2′κ(4) O (2):O (2′):O (5):O (5′))dizinc]

In the title polymeric complex, [Zn(2)(C(6)H(2)O(4)S)(2)(C(4)H(9)NO)(2)](n), each carboxyl­ate group of the thio­phene-2,5-dicarboxyl­ate dianion bridges a pair of inversion-related dimethyl­acetamide-coordinated Zn(II) atoms, generating a layer motif parallel to (101). The Zn(II) atom shows a distorted square-pyramidal coordination; the apical site is occupied by the O atom of the dimethyl­acetamide mol­ecule, whereas the four basal sites are occupied by carboxyl­ate O atoms. In the crystal, the dimethyl­acetamide mol­ecule is disordered over two positions in a 0.72 (1):0.28 (1) ratio in respect of the C atoms.
