Abstract
AbstractThe structure of the compound [Pt(NH3)4][PtI4] was studied by X‐ray diffractometry at 293 K (r. t.) and at 173 K. The structure is isotypic with that of Magnus' green salt and is unchanged at low temperature except for a slight contraction of the unit cell [tetragonal, P4/mnc; a = b = 9.8024(10) and c = 6.9311(10)Å at r. t; a = b = 9.764(3), c = 6.875(3)Å at 173 K]. It consists of [Pt(NH3)4]2+ cations and [PtI4]2− anions in which the platinum atoms are tetracoordinated by four ammine N or four I atoms in square‐planar arrangements. At 173 K the intramolecular bond lengths are hardly modified, but the intermolecular stacking interaction Pt‐Pt is slightly shortened.
