Characterization techniques (a) Single crystal X-ray diffraction Single crystal x-ray data for all crystals were collected on a Rigaku Mercury 375/M CCD (XtaLAB mini) diffractometer using graphite monochromator Mo-Kα radiation at 150 K and were processed with Rigaku crystal clear software. 1 Structure solution and refinement were performed using SHELX-2013 2 embedded in the WinGX suite. 3 Refinement of coordinates and isotropic thermal parameters of non-hydrogen atoms were carried out by the full-matrix least- squares method. Mercury version 3.5 was used for molecular representations and packing diagrams. 4 Acidic hydrogen atoms, especially in MRE, were located by difference Fourier maps while in other cases also at the calculated positions in the riding model. 1.
