The name of the mineral comes from the locality of Tripuhy, Ouro Preto, Minas Gerais, Brazil, where it was discovered.
Hussak and Prior[5] first described the mineral tripuhyite as an oxide of iron and antimony, and assigned it the composition Fe2Sb2O7.
[8] FeSbO4 exhibits the rutile structure, with a tetragonal unit cell.
The cations are octahedrally coordinated to oxygen anions, with the octahedra sharing edges along the c-direction.
Fe(III) and Sb(V) cations are distributed in a disordered way over the octahedral sites.
