Compound 4: For this compound, the DMAPY ligand was found to possess two strongly intercontorted positions. This double-position could not be described by a space group with higher symmetry, however and was thus identified as significant distortion. Besides, both TMSA ligands were found to be systematically disordered whereby the Si(CH3 Compound 11: The main disorder found in this compound is strongly related to the one found for compound 10. It needs to be highlighted again, that several samples were subjected to single crystal XRD analysis and that for all of them the same type of disorder was found. In analogy to the TBUAEDMA ligand, the TMSAEDMA ligand can fold itself around the Co(II) central ion in two different ways that need to be described by two parts to obtain a satisfying structure solution. The disorder was found for eight of thirteen molecules in the unit cell. Note the π-stacking interaction that can be seen from this extract. Short contact analysis revealed intermolecular π-H interactions as well as N-H and H-H interactions.
