σ-Hole triel bonds in aluminium derivatives

This communication reports the synthesis and X-ray characterization of a new mononuclear aluminium compound exhibiting an intramolecular sigma-hole triel bonding interaction. It is compared with a dinuclear aluminium compound, previously reported by us, where the aluminium atoms participate in two concurrent sigma-hole triel bonding interactions. To our knowledge, such behaviour has not been previously described in the literature.
