THE CRYSTAL STRUCTURE OF TELLURIUM DIOXIDE: A REDETERMINATION BY NEUTRON DIFFRACTION
Technical Report
·
OSTI ID:4802602
The crystal structure of tetragonal TeO/sub 2/ was studied using a neutron diffraction method. The space group is either P4/sub 1/2/sub 1/2 or P4/ sub 3/2/sub 1/2 and the lattice constants are of a = 4.796 A; c =7.626 A; c/a =1.59. New O atom parameters were determined. The coordination polyhedron of the Te atom is a distorted square pyramid. The Te-O distances are 1.91 A twice and 2.09 A (twice). The pyramids are linked by common O atoms. A geometrical similarity of Te atom arrangement to the rutile type of structure is discussed. (auth)
