Synthesis and Properties of a Methyl Derivative of Zeise's Dimer
Scott, John D.,Puddephatt, Richard J.
, p. 193 - 195 (1984)
A methyl(ethylene)platinum(II) complex has been prepared and characterized; it forms complexes where L = pyridine, Me2S, or C2H4, undergoes exchange with unsaturated reagents (un) where (un) = PhCH=CHPh, CH(CO2Me)=CH(CO2Me), or PhCCPh to give , undergoes insertion with CF3CCCF3 to give, after treatment with pyridine, (py)2>, and reacts with Zeise's dimer to give the unsymmetrical dimer .

Molecular platinum monochloride (PtCl) and platinum dichloride (PtCl2) have been prepared from platinum atoms and chlorine doped argon in a hollow-cathode sputtering device, matrix isolated in solid argon and characterized using electronic, infrared and X-ray absorption spectroscopies together with high level DFT calculations.

The heat capacity of crystalline α-platinum dichloride was measured for the first time in the temperature intervals from 11 to 300 K (vacuum adiabatic microcalorimeter) and from 300 to 620 K (differential scanning calorimetry). In the 300-620 K temperatur

The physicochemical characteristics of phase transitions of PtCl2 were investigated for the first time. The irreversible character of the transition from β-modification to α-form of PtCl2 and the temperature range of process were est
Thermodynamics of the Pt-Cl system
Chusova, Tamara P.,Semenova, Zinaida I.
, p. 59 - 64 (2008)
Using a static method three individual compounds in system of Pt-Cl: PtCl4, PtCl3, and PtCl2 are shown to exist. PtCl was shown not to exist. The enthalpies of formation of platinum chlorides were measured by calorimetry by reduction of the compounds with gaseous hydrogen. The recommended values for the enthalpies of formation at 298.15 K are -137.7 ± 0.3, 194.2 ± 1.0, and 245.6 ± 1.9 kJ/mol for PtCl2(s), PtCl3(s) and PtCl4(s), respectively.
Structure and bonding of the hexameric platinum(II) dichloride, Pt6Cl12 (β-PtCl2)
Von Schnering, Hans Georg,Chang, Jen-Hui,Peters, Karl,Peters, Eva-Maria,Wagner, Frank R.,Grin, Yuri,Thiele, Gerhard
, p. 516 - 522 (2008/10/08)
The crystal structure of Pt6Cl12 (β-PtCl2) was redetermined (R3m ah = 13.126 A, ch = 8.666 A, Z = 3; arh = 8.110 A, α = 108.04°; 367 hkl, R = 0.032). As has been shown earlier, the structure is in principle a hierarchical variant of the cubic structure type of tungsten (bcc), which atoms are replaced by the hexameric Pt6Cl12 molecules. Due to the 60° rotation of the cuboctahedral clusters about one of the trigonal axes, the symmetry is reduced from Im3m to R3m (I3m). The molecule Pt6Cl12 shows the (trigonally elongated) structure of the classic M6X12 cluster compounds with (distorted) square-planar PtCl4 fragments, however without metal-metal bonds. The Pt atoms are shifted outside the Cl12 cuboctahedron by Δ = +0.046 A (d(Pt-Cl) = 2.315 A; d(Pt-Pt) = 3.339 A). The scalar relativistic DFT calculations results in the full m3m symmetry for the optimized structure of the isolated molecule with d(Pt-Cl) = 2.381 A, d(Pt-Pt) = 3.468 A and Δ = +0.072 A. The electron distribution of the Pt-Pt antibonding HOMO exhibits an outwards-directed asymmetry perpendicular to the PtCl4 fragments, that plays the decisive role for the cluster packing in the crystal. A comparative study of the Electron Localization Function with the hypothetical trans-(Nb2Zr4)Cl12 molecule shows the distinct differences between Pt6Cl12 and clusters with metal-metal bonding. Due to the characteristic electronic structure, the crystal structure of Pt6Cl12 in space group R3m is an optimal one, which results from comparison with rhombohedral Zr6I12 and a cubic bcc arrangement.
