Crystal data were collected at 253 K on a Bruker AXS Quazar APEX II diffractometer using a 30 W air-cooled microfocus source (ImS) with focusing multilayer optics using MoKα radiation (wavelength = 0.71073 Å). Phi- and omega-scans were used. The structure was solved using intrinsic phasing method (ShelXT).³⁶ All non-hydrogen atoms were refined anisotropically using the least-square method on F².³⁷ Solvent molecule was disordered. Several restraints (SAME, SIMU, DELU) were applied to refine this molecule and to avoid the collapse of the structure during the least-squares refinement by the large anisotropic displacement parameters.

Crystal data were collected at low temperature (193K) on a Bruker-AXS SMART APEX II diffractometer (Ber + Lau -) and on a Bruker AXS Quazar APEX II diffractometer (Ber + AOT -, Ber + Tos -, Ber + TPB -, Ber + DS -, Ber + NTf2 -) using a 30 W air-cooled microfocus source (ImS) with focusing multilayer optics using MoK radiation (wavelength = 0.71073 Å). Phi-and omega-scans were used. The structures were solved by direct methods (ShelXS-97) or using an intrinsic phasing method (ShelXT). 51, 52 All non-hydrogen atoms were refined anisotropically using the least-square method on F 2 . 52 ORTEP molecular views are given in Figures S4 to S8 (Supplementary Information). Crystallographic data are given in Table 4.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
