The title complex, [Tb(C11H12N2O)(6)]I-3, has essentially the same structure at 160 K as at room temperature, and is clearly centrosymmetric without any disorder, contrary to some proposals regarding the possible mechanism of triboluminescence. Terbium has an octahedral coordination and lies in a position of (3) over bar symmetry, with all six antipyrine ligands crystallographically equivalent. One iodide anion lies in a special position of site symmetry (3) over bar, and another is on a threefold rotation axis, to give three iodide anions per terbium-centred complex cation.
