“…There is great current interest in the chemistry of reduced aluminum (Klemp et al, 2001, Bonyhady et al, 2018 and aluminum carbon (carbaalanes) clusters (Stasch et al, 2002;Uhl & Roesky, 2002;Kumar et al, 2004) as well as aluminumcarbon nanoparticles (Diaz-Droguett et al, 2020) because of their interesting structural chemistry and many theoretical studies have been carried out on potential derivatives and as analogs of the better known boron examples (Attia et al, 2017). This has lead to a renaissance in the chemistry of aluminum (Roesky, 2004).…”

In the title compound, [Al2Br4(CH2)(C4H10O)2], the molecule lies on a crystallographic twofold axis passing through the bridging C atom. Each AlIII atom is four-coordinate, being bonded to two bromide ions, bridging the CH2 group as well as the oxygen atom of a diethyl ether ligand in a slightly distorted tetrahedral arrangement with angles ranging from 101.52 (8) to 116.44 (5)°. The Al—CH2—Al angle, 118.4 (2)°, is the smallest observed for a structure where this moiety is not part of a ring. In the crystal, weak C—H...Br interactions, characterized as R 2 2(12) rings, link the molecules into ribbons in the [101] direction. The title compound is monomeric and coordinatively saturated in the solid state, as each aluminum is four-coordinate, but in solution the ether molecules from either or both Al atoms can dissociate, and would be expected to rapidly exchange, and this is supported by NMR data.
