MgLa2MoO6 crystallizes in the orthorhombic I222 space group. Mg(1) is bonded to four equivalent O(1) atoms to form distorted MgO4 tetrahedra that share edges with two equivalent Mo(1)O4 tetrahedra. La(1) is bonded in a 6-coordinate geometry to two equivalent O(1) and four equivalent O(2) atoms. Mo(1) is bonded to four equivalent O(1) atoms to form distorted MoO4 tetrahedra that share edges with two equivalent Mg(1)O4 tetrahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to one Mg(1), one La(1), and one Mo(1) atom. In the second O site, O(2) is bonded to four equivalent La(1) atoms to form a mixture of distorted corner and edge-sharing OLa4 tetrahedra.
MgLa2MoO6 crystallizes in the orthorhombic I222 space group. Mg(1) is bonded to four equivalent O(1) atoms to form distorted MgO4 tetrahedra that share edges with two equivalent Mo(1)O4 tetrahedra. All Mg(1)-O(1) bond lengths are 1.95 Å. La(1) is bonded in a 6-coordinate geometry to two equivalent O(1) and four equivalent O(2) atoms. Both La(1)-O(1) bond lengths are 2.52 Å. There are two shorter (2.27 Å) and two longer (2.83 Å) La(1)-O(2) bond lengths. Mo(1) is bonded to four equivalent O(1) atoms to form distorted MoO4 tetrahedra that share edges with two equivalent Mg(1)O4 tetrahedra. All Mo(1)-O(1) bond lengths are 1.97 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to one Mg(1), one La(1), and one Mo(1) atom. In the second O site, O(2) is bonded to four equivalent La(1) atoms to form a mixture of distorted corner and edge-sharing OLa4 tetrahedra.
