X-ray diffraction Single crystal X-ray diffraction data for compound 4c were collected on an Bruker D8 Venture diffractometer at room temperature, using graphite monochromatic MoKα radiation (λ = 0.71069 Å). Data collection and cell refinement were performed with Bruker Instrument Service v4.2.2 and APEX2 [ i ], respectively. Data reduction was carried out using SAIT [ ii ]. Empirical multiscan absorption correction using equivalent reflections was performed with the SADABS program [ iii ]. The structure solutions and full-matrix least-squares refinements based on F 2 were performed with the SELXS-97 and SELXL-97 program packages [iv]. All atoms except hydrogen were refined anisotropically. ydrogen atoms were treated by a mixture of independent and constrained refinement. The structure was drawn by Mercury program [v]. Details of data collection and refinement are listed in Table S1. Table S1: Summary of crystal data and structure refinement of compound 4c.
