Poly[bis-(N,N-dimethyl-acetamide)-1κO,2κO-bis-(μ(4)-thio-phene-2,5-di-car-boxyl-ato-1:2:1':2'κO:O:O:O)dizinc].
In the title polymeric complex, [Zn(2)(C(6)H(2)O(4)S)(2)(C(4)H(9)NO)(2)](n), each carboxyl-ate group of the thio-phene-2,5-dicarboxyl-ate dianion bridges a pair of inversion-related dimethyl-acetamide-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 dimethyl-acetamide mol-ecule, whereas the four basal sites are occupied by carboxyl-ate O atoms. In the crystal, the dimethyl-acetamide mol-ecule is disordered over two positions in a 0.72 (1):0.28 (1) ratio in respect of the C atoms.
