Abstract
Treatment of p-tert-butylcalix[4]arene 1 with [H3Al(NMe3)]2 results in trimetallation and deprotonation by the tertiary amine, yielding the bis(calix[4]arene), [{(1– H4)Al}2]2–[HNMe3]+ 2, 2, which has been isolated with included methylene chloride; distorted five-coordinate O-bound aluminium centres [Al–O 1.74(1)–2.35(1)Å] fuse the slightly flattended cone calixarene units with the methylene chloride H-atoms residing over two opposite aromatic rings in each cone, C ⋯ ring centroid 3.54 Å.Keywords
