Poly[dimethylammonium [bis(dimethylamine)tri-₄-terephthalato-sodium(I)dizinc(II)]]

Abstract: 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 dimethylamine molecule; together with bonding from the O atoms of the three terephthalate groups, the geometry is tetrahedral. 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 dimethylammonium cations. The organic cation is disordered about a centre of inversion.
