Abstract
The temperature dependence of the saturated vapor pressure of the trans-Pt(ktf)2 complex obtained from fluorinated β-ketoimine (CF3-CO-CH2-C(NH)-CH3) was studied by the flow method. The standard thermodynamic parameters ΔH T0 and ΔS T0 of sublimation have been determined. Full crystal-chemical study has been performed for the complex. Crystal data for C10H10F6N2O2Pt: a = 5.9790(8) Å, b = 7.373(2) Å, c = 8.5767(2) Å,α = 84.05(2)°, β = 72.43(1)°, γ = 67.14(1)°, V = 332.1(1) Å3, Z = 1, d calc = 2.496 g/cm3, triclinic, space group \(P\bar 1\). The structure is molecular and consists of isolated trans-Pt(ktf)2 complexes. The Pt atom lies at the symmetry center and has a square planar environment of two oxygen and two nitrogen atoms; the distances Pt-O (1.984 Å) and Pt-N (1.969 Å) are similar within the limits of 2σ; the OPtN bond angle is 93.9°. Molecular packing in crystal is considered based on structural data; van der Waals energy of the crystal lattice of trans-Pt(ktf)2 was calculated by the atom-atom potential method.
