The bowl-shaped aromatic azaacepentalenide anion and its perchloro analogue were derived from 10-azatriquinacene and 2,3,5,6,8,9-hexachloro-10-azatriquinacene via the N-oxides. Spectroscopic and computational studies, as well as chemical derivitization experiments, were used to confirm the structural assignments.
