The structure described by ZnTa2O6 crystallizes in the orthorhombic Pmn2_1 space group. Ta(1) is bonded to one O(3), one O(4), two equivalent O(1), and two equivalent O(2) atoms to form corner-sharing TaO6 octahedra. The corner-sharing octahedral tilt angles range from 25-43°. Zn(1) is bonded in a 4-coordinate geometry to one O(3), one O(4), and two equivalent O(1) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to two equivalent Ta(1) and one Zn(1) atom. In the second O site, O(2) 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 distorted trigonal non-coplanar geometry to two equivalent Ta(1) and one Zn(1) atom. In the fourth O site, O(4) is bonded in a T-shaped geometry to two equivalent Ta(1) and one Zn(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
