(MoO3)3H2O crystallizes in the triclinic P-1 space group. The structure consists of two water molecules inside a MoO3 framework. In the MoO3 framework, there are three inequivalent Mo sites. In the first Mo site, Mo(1) is bonded in a 6-coordinate geometry to one O(4), one O(7), one O(8), and three equivalent O(1) atoms. In the second Mo site, Mo(2) is bonded to one O(5), one O(8), one O(9), and three equivalent O(2) atoms to form a mixture of distorted corner and edge-sharing MoO6 octahedra. The corner-sharing octahedral tilt angles are 32°. In the third Mo site, Mo(3) is bonded in a 6-coordinate geometry to one O(6), one O(7), one O(9), and three equivalent O(3) atoms.
