Abstract
In the title compound, (C5H7N2)5[TeV9O28], the tellurium and vanadium atoms are statistically disordered over two of the ten metal-atom sites in the [TeV9O28]5– heteropolyanion. The anions stack along [100] and are extended into a three-dimensional supramolecular network through N—H...O and weak C—H...O hydrogen bonds involving the self-assembled 2-aminopyridinium pentamers, which are linked by C—H...π and π–π stacking interactions. The most important contributions to the Hirshfeld surface arise from O...H/H...O (54.8%), H...H (17.8%) and C...H/H...C (13.4%) contacts.
