diffraction (SCXRD) measurements were performed at room temperature
on a Bruker D8 Venture diffractometer operating at 50 kV and 1.4 mA
equipped with a Photon 3 CMOS detector, a flat graphite monochromator,
and a Mo Kα IμS 3.0 microfocus source (λ = 0.71073
Å). The raw frame data were collected using the Bruker APEX3
software package (Bruker AXS, 2015), while the frames were integrated
with the Bruker SAINT program using a narrow-frame algorithm for the
integration of the data; absorption effects were corrected using the
multi-scan method (SADABS).28 (link) Initial models
of the crystal structures were obtained with the program SHELXT-201429 (link) and refined using the program SHELXL-201430 (link) within the APEX3 software package. The atomic
displacement parameters were refined anisotropically for all atoms.
Diamond (Crystal Impact Gmbh, 2015) was used for the structure visualization.
