[0032] (1) Structure determination of complexes

[0033] A single crystal with a size of 0.18 mm × 0.17 mm × 0.16 mm was selected using a BRUKER SMART 1000 X-ray single crystal diffractometer, and Mo K alpha radiation ( lambda = 0.071 073 nm) as a diffraction light source, at 293 (2) K temperature, with φ - ω scan mode, in 1.47 θ ≤ θ ≤ 25.01 θ (-11≤ h ≤11, -12≤ k ≤ 12, -17 ≤ l ≤ 11), a total of 7859 diffraction points were collected, of which 4745 independent diffraction points [I > 2 α(I)](R int = 0.0177). The crystal structure was solved by the direct method, and the non-hydrogen atoms were obtained by the difference Fourier synthesis method. The method of determining and correcting the hydrogen atoms was theoretical hydrogenation, and the isotropic and anisotropic thermal parameters were used for the hydrogen atoms and non-hydrogen atoms. The structure is corrected by the full matrix least squares method, and all calculations are completed with SHELXS-9...
