MoAsO5 crystallizes in the orthorhombic P2_12_12_1 space group. Mo(1) is bonded in a 5-coordinate geometry to one O(1), one O(4), one O(5), and two equivalent O(2) atoms. As(1) is bonded in a tetrahedral geometry to one O(2), one O(3), one O(4), and one O(5) atom. There are five inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one Mo(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to two equivalent Mo(1) and one As(1) atom. In the third O site, O(3) is bonded in a single-bond geometry to one As(1) atom. In the fourth O site, O(4) is bonded in a bent 120 degrees geometry to one Mo(1) and one As(1) atom. In the fifth O site, O(5) is bonded in a bent 120 degrees geometry to one Mo(1) and one As(1) atom.
