A new layered zinc phosphate templated by protonated isonicotinate, [Zn2(C6H5NO2)2(HPO4)2].

ABSTRACT

An organic-inorganic hybrid compound, poly[bis[(pyridine-4-carboxylato)zinc(II)]-di-mu3-phosphato], [Zn2(C6H5NO2)2(HPO4)2], has been hydrothermally synthesized and structurally characterized. The crystal structure consists of two types of two-dimensional layers of zinc hydrogenphosphate templated by protonated isonicotinate (ina) (or 4-pyridinecarboxylic acid), which contain two crystallographically independent centrosymmetric [Zn2(ina)2(HPO4)2] dimers as basic building units. The layers are interconnected via hydrogen-bonding and heterocyclic ring interactions.
