Tris[3,6‐di‐tert‐butyl‐1‐(isoquinolin‐1‐yl)naphthalen‐2‐olato‐κ2N,O]aluminium(III) toluene sesquisolvate
Abstract:The central AlIII atom of the title compound, [Al(C27H28NO)3]·1.5C7H8, has octahedral geometry in which the three N atoms are arranged in a meridional fashion. One of the toluene solvent molecules is located on a general position, while the second is disordered around a centre of inversion. The ligand molecule has axial chirality, and two of the three ligands in the complex exhibit the same stereochemistry. The three independent chelate rings exhibit significantly different bite angles at the metal atom, with one [83.72 (8)°] notably smaller than the other two [87.22 (8) and 87.13 (8)°]. Calculation of the solid angle covered by the ligands at the metal atom reveals that coverage is greatest for the ligand group with the shortest Al—O bond distance.
