Treatment of indolyl-3-aldimines (3-^tBuN=CH)C₈H₅NH with AlMe₃ afforded the deprotonated indolyl aluminum complex cis-[(μ-η¹:η¹-3-^tBuN=CH)C₈H₅NAlMe₂]₂, and its crystal structure was determined by X-ray single-crystal diffraction. The crystal belongs to the orthorhombic system, space group P2₁2₁2 with a = 14.590(9), b = 15.860(2), c = 13.266(8) Å, μ = 0.118 mm^-1, M_r = 512.64, V = 3069.5(3) Å³, Z = 4, D_c= 1.109 g/cm³, F(000) = 1104, R = 0.0451 and wR = 0.0937 for 4978 observed reflections with I > 2σ(I). In addition, the title compound exhibited a high catalytic activity toward the addition of amines to carbodiimide to form guanidines.
