A suitable crystal of the Pt(DPP)(acac) complex was obtained by slow evaporation of the CH2Cl2–isobutanol solution at room temperature. Single crystal X-ray diffraction data of the complex were collected using a Bruker SMART 1000 CCD diffactometer with graphite monochromated Mo Kα radiation (λ = 0.71073 Å using the ω scan mode at 298(2) K. Intensity data were corrected for Lp factors and empirical absorption. The structure was solved by direct methods and expanded by using Fourier differential techniques with SHELXTL. All non-hydrogen atoms were located with successive difference Fourier syntheses. The hydrogen atoms were geometrically fixed and allowed to ride on the parent atoms to which they are attached. The structure was refined by full-matrix least-squares method on F2 with anisotropic thermal parameters for all non-hydrogen atoms. Atomic scattering factors and anomalous dispersion corrections were taken from international tables for X-ray crystallography. |
