The crystal structure of Na3[Tb(C7H3NO4)3].NaClO4.6H2O has been determined by single crystal X-ray diffraction. The compound crystallizes in the hexagonal space group P (6) over bar 2c, with a=10.442(3) Angstrom, c=18.346(7) Angstrom and Z=2. Refinement of the crystal structure on basis of 722 observed reflections led to R(1)=0.067. The coordination polyhedron around terbium is a distorted tricapped trigonal prism with D3 symmetry.
