A New Mixed-valence Iodoplatinate(II, IV) (NH3Me)4Pt3I11 with PtI6, PtI4, and Pt2I6 Anions in the Crystal StructureThe mixed-valence iodoplatinate(II, IV) (NH3Me)4Pt3I11 has been obtained from aqueous solutions by reactions of H2PtCl6 with N2H4 · 2 HCl and NH3MeI. The monoclinic crystal structure contains planar Pt2I62- anions side by side with PtI62- and PtI42- anions, which are connected by asymmetric iodide bridges to ∞1[PtI4I2/2]-chains.
Notes:
Schwarze Kristalle des gemischtvalenten Iodoplatinats(II, IV) (NH3Me)4Pt3I11 wurden aus wäßrigen Lösungen durch Reaktion von H2PtCl6 mit N2H4 · 2 HCl und NH3MeI erhalten. Am Aufbau der monoklinen Kristallstruktur (RG C2/m; a = 1 531,35(27) pm; b = 2 033,3(4) pm; c = 1 178,51(12) pm; β = 115,33(13)°; Z = 4) sind neben planaren Pt2I62--Anionen auch PtI62-- und PtI42--Anionen beteiligt, welche über asymmetrische Iodbrücken zu ∞1[PtI4I2/2]-Ketten verknüpft sind.
