Abstract

The crystal structure of Cs₂[Zn(NO₂)₄] has been determined by X-ray diffraction. Each nitrite ion in the Zn(NO ₂)₄^2- group forms one short [2.080(3) Å] and one long [2.516(3) A] Zn-O bond, the metal-ligand interaction being intermediate between symmetrical chelation and syn-unidentate nitrite coordination. It seems likely that this unsymmetrical geometry is adopted in order to minimize ligand-ligand repulsions, though density functional theory calculations suggest a very shallow potential energy curve for the complex.
