The compound described by Ta2O5 crystallizes in the orthorhombic Pbam space group. Ta(1) is bonded to one O(3), two equivalent O(1), and two equivalent O(2) atoms to form distorted corner-sharing TaO5 trigonal bipyramids. There are three inequivalent O sites. In the first O site, O(2) is bonded in a bent 150 degrees geometry to two equivalent Ta(1) atoms. In the second O site, O(1) is bonded in a bent 150 degrees geometry to two equivalent Ta(1) atoms. In the third O site, O(3) is bonded in a linear geometry to two equivalent Ta(1) atoms. is represented by the CIF card [CIF]
