The material described by Yb2Mo4O15 crystallizes in the monoclinic P2_1/c space group. Yb(1) is bonded to one O(1), one O(2), one O(3), one O(5), one O(6), one O(7), and one O(8) atom to form YbO7 pentagonal bipyramids that share corners with four equivalent Mo(1)O4 tetrahedra. There are two inequivalent Mo sites. In the first Mo site, Mo(1) is bonded to one O(2), one O(3), one O(5), and one O(8) atom to form MoO4 tetrahedra that share corners with four equivalent Yb(1)O7 pentagonal bipyramids. In the second Mo site, Mo(2) is bonded in a 5-coordinate geometry to one O(1), one O(4), one O(6), one O(7), and one O(8) atom. There are eight inequivalent O sites. In the first O site, O(7) is bonded in a bent 150 degrees geometry to one Yb(1) and one Mo(2) atom. In the second O site, O(8) is bonded in a 3-coordinate geometry to one Yb(1), one Mo(1), and one Mo(2) atom. In the third O site, O(1) is bonded in a bent 150 degrees geometry to one Yb(1) and one Mo(2) atom. In the fourth O site, O(2) is bonded in a linear geometry to one Yb(1) and one Mo(1) atom. In the fifth O site, O(3) is bonded in a bent 150 degrees geometry to one Yb(1) and one Mo(1) atom. In the sixth O site, O(4) is bonded in a linear geometry to two equivalent Mo(2) atoms. In the seventh O site, O(5) is bonded in a bent 150 degrees geometry to one Yb(1) and one Mo(1) atom. In the eighth O site, O(6) is bonded in a bent 120 degrees geometry to one Yb(1) and one Mo(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
