MoO3 crystallizes in the orthorhombic Pnma space group. Mo(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form corner-sharing MoO6 octahedra. The corner-sharing octahedral tilt angles range from 26-27°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to two equivalent Mo(1) atoms. In the second O site, O(2) is bonded in a bent 150 degrees geometry to two equivalent Mo(1) atoms.
MoO3 crystallizes in the orthorhombic Pnma space group. Mo(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form corner-sharing MoO6 octahedra. The corner-sharing octahedral tilt angles range from 26-27°. Both Mo(1)-O(2) bond lengths are 1.90 Å. There are two shorter (1.89 Å) and two longer (1.90 Å) Mo(1)-O(1) bond lengths. There are two inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to two equivalent Mo(1) atoms. In the second O site, O(2) is bonded in a bent 150 degrees geometry to two equivalent Mo(1) atoms.
