YbTl(MoO4)2 crystallizes in the orthorhombic Pnma space group. Yb(1) is bonded to one O(2), one O(4), two equivalent O(5), and two equivalent O(6) atoms to form YbO6 octahedra that share corners with three equivalent Mo(1)O4 tetrahedra and corners with three equivalent Mo(2)O4 tetrahedra. There are two inequivalent Mo sites. In the first Mo site, Mo(1) is bonded to one O(1), one O(2), and two equivalent O(6) atoms to form MoO4 tetrahedra that share corners with three equivalent Yb(1)O6 octahedra.
