Cu-Kα (λ = 1.54184 Å) radiation was used to collect the X-ray reflections of the crystal. Data reduction was performed using CrysAlisPro 171.33.55 software. S1 Structures were solved and refined using SHELXL-97 S2 with anisotropic displacement parameters for non-H atoms. Hydrogen atoms on O and N were experimentally located in difference electron density maps. All C−H atoms were fixed geometrically using HFIX command in SHELX-TL with anisotropic displacement parameters for non-H atoms. All H atoms of 4 and 5.DN were fixed geometrically. Empirical absorption correction was done using spherical harmonics, implemented in SCALE3 ABSPACK scaling algorithm. A check of the final CIF file using PLATON S3 did not show any missed symmetry. In case of 5.DN some solvent accessible voids were observed. The contribution to the scattering factors from this was removed by SQUEEZE S4 in PLATON. PLATON was used as incorporated in WinGX.
