Aluminum dimer containing bulky 1,2,3-triazolate ligand

The first molecular aluminum 1,2,3-triazolato complex was synthesized bearing a bulky 1,2,3-triazolate ligand. oligomers and polymers were avoided due to the bulkiness and noncoordinating nature of the substituents. the novel al2n4 ring formed contains symmetrical al-n bond distances unexpectedly having asymmetric al-n-n angles of 144.55(15)° and 115.83(14)°. this asymmetry demonstrates the effect of the steric hindrance of the ligand. copyright © 2014 issam kobrsi.
