| Zusammenfassung: | <jats:p>The structure of the title complex, [CrCl<jats:sub>2</jats:sub>(2,3,2-tet)]ClO<jats:sub>4</jats:sub>(2,3,2-tet is 1,4,8,11-tetraazaundecane, C<jats:sub>7</jats:sub>H<jats:sub>20</jats:sub>N<jats:sub>4</jats:sub>), has been determined from synchrotron data. The Cr<jats:sup>III</jats:sup>ion is coordinated by the four N atoms of the 1,4,8,11-tetraazaundecane ligand in the equatorial plane and two chloride ions in an axial arrangement, displaying a slightly distorted octahedral coordination environment. The two H atoms of the secondary amines are grouped on the same side of the equatorial N<jats:sub>4</jats:sub>plane (<jats:italic>meso</jats:italic>-<jats:italic>RS</jats:italic>conformation). The Cr—N bond lengths range from 2.069 (2) to 2.084 (2) Å, while the mean Cr—Cl bond length is 2.325 (2) Å. The crystal structure is stabilized by intermolecular hydrogen-bonding interactions between the primary and secondary amine groups of the 2,3,2-tet ligands, the Cl ligands and the O atoms of the perchlorate counter-anion, forming corrugated layers parallel to (010).</jats:p> |
