Fig. 5. Molecular structure of compound 7 in the solid state. Ellipsoids are set at the 50% probability level; hydrogen atoms and co-crystallised solvent molecules are omitted for clarity and NHC ligands and iso-propyl groups are depicted in wireframe for simplicity. Selected bond lengths (Å) and angles (°): Al(1)–C(1) 2.042(7), Al(1)–C(16) 2.109(3), Al(1)–C(27) 2.059(3), C(27)–N(3) 1.292(4), Al(1)–C(27)–Al(1′) 91.59(11), C(27)–Al(1)–C(27′) 82.74(11), C(27)–N(3)–C(28) 126.3(2).
