The three terephthalate groups in the title polymeric coordination compound, {(C2H8N)[NaZn2(C8H4O4)3(C2H7N)2]} n , lie on inversion centers. One functions as a bridge to two Na and two Zn atoms. The O atoms of the other two terephthalate groups bind to only one Zn atom. The Zn atom is additionally coordinated by a dimethyl-amine mol-ecule; together with bonding from the O atoms of the three terephthalate groups, the geometry is tetra-hedral. The manner of bridging of the terephalate groups gives rise to a polyanionic honeycomb sheet motif; the sheets are held into a three-dimensional network through the Na atoms. The cavities in the network are occupied by the dimethyl-ammonium cations. The organic cation is disordered about a centre of inversion. © International Union of Crystallography 2007.
