title: Hexakis(antipyrine-O)terbium(III) triperchlorate.
abstract: In the title compound, hexakis(1,2-dihydro-1,5-dimethyl-2-phenyl-3H-pyrazol-3-one-O)terbium(III) triperchlorate, [Tb(C(11)H(12)N(2)O)(6)](ClO(4))(3), the Tb atom lies on a site of $\overline 3$ crystallographic symmetry and the unique Tb-O distance is 2.278 (2) A. One of the perchlorate anions has threefold crystallographic symmetry, while the other is disordered about a $\overline 3$ site.
