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 P\overline 421c was confirmed by the structure solution and refinement.
