A single-strand polymer of hexacoordinated zinc(II) phosphodiester complex

The structure of the title compound 2, catena-poly{aqua(dimethylformamide-O)bis{μ-[bis(p-nitrophenyl)phosphato]}zinc(II) mono(dimethylformamide)}, consists of linear polymers in which adjacent Zn2+ cations are joined by the oxygen atoms of two bidentate bridging phosphate diester ligands 1. The metal shows an octahedral coordination geometry with the zinc connected to six O atoms, four belonging to four different surrounding phosphate groups, one to a water molecule and one to a DMF molecule. Each single-strand is built-up from Zn octahedrons having alternate configuration Δ or Λ.
