MoO2 crystallizes in the orthorhombic Cmcm space group. Mo(1) is bonded to one O(2), two equivalent O(3), and three equivalent O(1) atoms to form a mixture of distorted edge and corner-sharing MoO6 octahedra. The corner-sharing octahedral tilt angles range from 0-32°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a trigonal non-coplanar geometry to three 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. In the third O site, O(3) is bonded in a square co-planar geometry to four equivalent Mo(1) atoms.

The corner-sharing octahedral tilt angles range from 0-32°. The Mo(1)-O(2) bond length is 1.91 Å. Both Mo(1)-O(3) bond lengths are 2.23 Å. There are two shorter (2.06 Å) and one longer (2.11 Å) Mo(1)-O(1) bond length. There are three inequivalent O sites. In the first O site, O(1) is bonded in a trigonal non-coplanar geometry to three 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. In the third O site, O(3) is bonded in a square co-planar geometry to four equivalent Mo(1) atoms.
