Mo3O10 crystallizes in the orthorhombic Aea2 space group. There are two inequivalent Mo sites. In the first Mo site, Mo(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(6) atoms. In the second Mo site, Mo(2) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(4), one O(5), and two equivalent O(3) atoms. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 150 degrees geometry to one Mo(1) and one Mo(2) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Mo(1) and one Mo(2) atom. In the third O site, O(3) is bonded in a distorted linear geometry to two equivalent Mo(2) atoms. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to two equivalent Mo(2) atoms. In the fifth O site, O(5) is bonded in a linear geometry to two equivalent Mo(2) atoms. In the sixth O site, O(6) is bonded in a single-bond geometry to one Mo(1) atom.
