Bis(-N-methylethylamido)bis[tert-butylchloroaluminium]

E. Hecht

Abstract: The dimeric title coordination compound, [Al₂(C₄H₉)₂Cl₂(C₃H₈N)₂], comprises tetrahedral Al atoms each bonded to two N atoms of the amide ligands, one C atom of the tert-butyl group and one Cl atom. The Al atoms are bridged by amide moieties, creating a planar four-membered Al₂N₂ ring, which may be considered as the main structural feature. A twofold rotation axis passes through the centre of the ring. The Al-N bond distance are 1.943  (4) and 1.962  (4)  Å. Pseudosymmetry in space group P4₂/nmc was considered but the space group P2₁c was confirmed by the structure solution and refinement.
