TiO2 crystallizes in the orthorhombic Pnma space group. Ti(1) is bonded in a 5-coordinate geometry to two equivalent O(2) and three equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Ti(1) atoms. In the second O site, O(2) is bonded in a bent 150 degrees geometry to two equivalent Ti(1) atoms.
TiO2 crystallizes in the orthorhombic Pnma space group. Ti(1) is bonded in a 5-coordinate geometry to two equivalent O(2) and three equivalent O(1) atoms. There is one shorter (1.77 Å) and one longer (1.86 Å) Ti(1)-O(2) bond length. There are two shorter (1.94 Å) and one longer (2.00 Å) Ti(1)-O(1) bond length. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Ti(1) atoms. In the second O site, O(2) is bonded in a bent 150 degrees geometry to two equivalent Ti(1) atoms.
