Molecular structures of complexes 2, 3, 5–8 which formed good quality crystals have been solved by X-ray Crystallography; the quality of other complexes was poor. The crystal of a complex was mounted on a polymer loop and data were measured on a Rigaku-Oxford Diffraction (2, 5–8), Agilent, Eos, Gemini diffractometer (3) at 173(2) (3, 8) and 293(2) (2, 5–7) K. The diffractometer was equipped with a graphite monochromator with Mo–Kα radiation (λ = 0.71073 Å; 3, 8), or Cu-Kα radiation (λ = 1.54178 Å; 2, 5–7). The data collection and cell refinement were processed with CrysAlisPro while data reduction was processed with CrysAlisRED (2, 3, 5–8).67 The structures were solved by the direct methods and refined using full-matrix least-squares techniques based on F2 using ShelXL-2008, 2015.68,69 (link)Table 4 contains crystal data.

The data were collected on a Gemini diffractometer (Agilent Technologies) using Mo-K α radiation (λ = 71.073 pm), ω-scan rotation. Data reduction was performed with the CrysAlisPro (CrysAlisPro: Data collection and data reduction software package, Agilent Technologies) including the program SCALE3 ABSPACK (SCALE3 ABSPACK: Empirical absorption correction using spherical harmonics) for empirical absorption correction. The structures were solved by direct methods with SIR92. 22 The refinement of all non-hydrogen atoms was performed with SHELXL-97. 23 The structure figures were generated with Diamond. 24 CCDC 990595 (endo-9d), 989748 (12a), 989750 (12b), 989749 (13a), 989751 ((R)-13b), 989752 ((S)-13b), 989753 (14a), 989754 (14b) and 989755 (18) contain the supplementary crystallographic data for this paper.
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.
