Description / Table of Contents:
Preparation and Crystal Structure of PtI3, a Mixed-valence Platinum (II, IV) IodidePtI3 was obtained by thermal decomposition of PtI4 in a closed system at 300°C and 8 atm iodine pressure. Single crystals were formed by the reaction of PtI4 with aqueous solutions of KI and I2 at 270°C. The crystal structure of the monoclinic compound (a = 673.5(2) pm; b = 1206.1(4) pm; c = 1331.3(5) pm; β = 101.25(6)°; Z = 8; space group C2/c-C2h6) contains square planar PtI4 and octahedral PtI6 groups which are connected by common edges to chains.
Notes:
PtI3 entsteht beim thermischen Abbau von PtI4 im geschlossenen System bei 8 atm I2-Druck und Temperaturen um 300°C. Einkristalle der Verbindung wurden durch Umsetzung von PtI4 mit KI und I2 in wäßriger Lösung bei 270°C erhalten. In der Kristallstruktur der monoklinen Verbindung (a = 673,5(2) pm; b = 1206,1(4) pm; c = 1331,3(5) pm; β = 101,25(6)°; Z = 8; Raumgruppe C2/c-C2h6) sind planare PtI4- und oktaedrische PtI6-Baugruppen über gemeinsame Kanten zu Ketten verknüpft.
