Usage

Uses

Platinum(II) iodide is used in pharmaceuticals and medical applications. It is also used to form cis and trans complexes with propan-1-amine. It is utilized in the catalytic hydration reaction of alkynes such as 2-hexyne, 4-methyl-2-pentyne, and 4,4dimethyl-2- pentyne . It is also used in the preparation of diiodo(2,9-dimethyl-1,10-phenanthroline)platinum(II).

Ternary arsenides based on platinum-indium and palladium-indium fragments of the Cu3Au-type: Crystal structures and chemical bonding

Three metal-rich palladium-indium and platinum-indium arsenides, Pd5InAs, Pt5InAs, and Pt8In2As, were synthesized using a high-temperature ampoule technique. Their crystal structures were determined from Rietveld analysis of powder diffraction data. All the compounds crystallize in tetragonal system with P4/mmm space group (Pd5InAs: a = 3.9874(1) ?, c = 6.9848(2) ?, Z = 1, Rp = 0.053; Rb = 0.013; Pt5InAs: a = 3.9981(2) ?, c = 7.0597(4) ?, Z = 1, Rp = 0.058, Rb = 0.016; Pt8In2As: a = 3.9872(3) ?, c = 11.1129(7) ?, Z = 1, Rp = 0.047; Rb = 0.014). The first two compounds belong to the Pd5TlAs structure type, while the third one is isotypic with the recently discovered Pd8In2Se. Main structural units in all arsenides are indium-centered [TM12In] cuboctahedra (TM = Pd, Pt) of the Cu3Au type, single- and double-stacked along the c axis in TM5InAs and Pt8In2As, respectively, alternating with [TM8As] rectangular prisms. DFT electronic structure calculations predict all three compounds to be 3D metallic conductors and Pauli-like paramagnets. According to the bonding analysis based on the electron localization function and electron localizability indicator topologies, all compounds feature multi-centered interactions between transition metal and indium in their heterometallic fragments. Additionally, pairwise interactions between platinum atoms are also observed, indicating a somewhat more localized bonding in the case of platinum-based compounds.

Determination of temperature dependent partial pressures in closed systems - A new method. The heat of formation for PtI2(s)

A new method to determine temperature dependent partial pressures of gaseous species in equilibria with condensed phases in closed systems (silica ampoules) at temperatures up to 1000°C and pressures pi 0.01 i 2. The heat of formation and the entropy of PtI2(s) (ΔBHo(PtI2(s), 298) = -51.4 kJ · mol-1, So(PtI2(s), 298) = 119.3 J · K-1 · mol-1) are computed from experimental results. The heat of thermal decomposition of PtI2(s) was reconsidered by Knudsen Mass Spectrometry.

Interaction of Platinum(II) Complexes with Methyl Red

The interaction of K2[PtCl4], K2[PtI4], [PtThio4]Cl2, cis- and trans-[Pt(NH3)2Cl2], and [Pt(NH3)4]Cl2 with Methyl Red (HL) was studied. It was found that HL forms stable complexes, where it may be a mono- or bidentate ligand. The thermodinamical stability of trans-[Pt(NH3)2(LH)Cl]NO3 was studied potentiometrically. The results obtained show that the azo group possesses π acceptor abilities.
