The structure described by MoO2 is Hydrophilite-like structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Mo sites. In the first Mo site, Mo(1) is bonded to one O(4), two equivalent O(2), and three equivalent O(3) atoms to form a mixture of distorted corner and edge-sharing MoO6 octahedra. The corner-sharing octahedral tilt angles range from 51-55°. In the second Mo site, Mo(2) is bonded to one O(2), two equivalent O(4), and three equivalent O(1) atoms to form a mixture of corner and edge-sharing MoO6 octahedra. The corner-sharing octahedral tilt angles range from 51-55°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a trigonal non-coplanar geometry to three equivalent Mo(2) atoms. In the second O site, O(2) is bonded in a trigonal planar geometry to one Mo(2) and two equivalent Mo(1) atoms. In the third O site, O(3) is bonded in a trigonal non-coplanar geometry to three equivalent Mo(1) atoms. In the fourth O site, O(4) is bonded in a trigonal planar geometry to one Mo(1) and two equivalent Mo(2) atoms. is represented by the CIF card [CIF]
