Ta2O5 crystallizes in the tetragonal I4/mmm space group. Ta(1) is bonded to one O(1) and four equivalent O(2) atoms to form distorted corner-sharing TaO5 trigonal bipyramids. There are two inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to two equivalent Ta(1) atoms. In the second O site, O(2) is bonded in a linear geometry to two equivalent Ta(1) atoms.
Ta2O5 crystallizes in the tetragonal I4/mmm space group. Ta(1) is bonded to one O(1) and four equivalent O(2) atoms to form distorted corner-sharing TaO5 trigonal bipyramids. The Ta(1)-O(1) bond length is 1.90 Å. All Ta(1)-O(2) bond lengths are 1.94 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to two equivalent Ta(1) atoms. In the second O site, O(2) is bonded in a linear geometry to two equivalent Ta(1) atoms.
