Magnus’ green salt is the chemical compound with the formula [Pt(NH3)4][PtCl4]. This species has been of interest in materials chemistry and solid-state physics because of its one-dimensional structure. It contains a linear chain of alternating [PtCl4]2− anions and [Pt(NH3)4]2+ cations in which the platinum atoms are separated by 3.25 Å. It is a semi-conductor. The compound may be prepared by mixing aqueous solutions of [Pt(NH3)4]2+ and [PtCl4]2− to obtain a deep green precipitate.
