Ta2O5 crystallizes in the monoclinic C2 space group. Ta(1) is bonded to one O(1), two equivalent O(2), and two equivalent O(3) atoms to form a mixture of corner and edge-sharing TaO5 trigonal bipyramids. There are three 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. In the third O site, O(3) is bonded in a water-like geometry to two equivalent Ta(1) atoms.

Ta(1) is bonded to one O(1), two equivalent O(2), and two equivalent O(3) atoms to form a mixture of corner and edge-sharing TaO5 trigonal bipyramids. The Ta(1)-O(1) bond length is 1.93 Å. There is one shorter (1.90 Å) and one longer (1.94 Å) Ta(1)-O(2) bond length. There is one shorter (1.87 Å) and one longer (2.08 Å) Ta(1)-O(3) bond length. There are three inequivalent O sites.
