The structure described by MgHo(MoO3)2 crystallizes in the monoclinic Pc space group. Mg(1) is bonded in a distorted rectangular see-saw-like geometry to one O(1), one O(4), one O(5), and one O(6) atom. Ho(1) is bonded in a 8-coordinate geometry to one O(1), one O(2), one O(3), one O(6), two equivalent O(4), and two equivalent O(5) atoms. There are two inequivalent Mo sites. In the first Mo site, Mo(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form corner-sharing MoO6 octahedra. The corner-sharing octahedral tilt angles range from 42-47°. In the second Mo site, Mo(2) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form corner-sharing MoO6 octahedra. The corner-sharing octahedral tilt angles range from 42-47°. There are six inequivalent O sites. In the first O site, O(1) is bonded to one Mg(1), one Ho(1), one Mo(1), and one Mo(2) atom to form distorted corner-sharing OHoMgMo2 trigonal pyramids. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Ho(1), one Mo(1), and one Mo(2) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Ho(1), one Mo(1), and one Mo(2) atom. In the fourth O site, O(4) is bonded in a 5-coordinate geometry to one Mg(1), two equivalent Ho(1), one Mo(1), and one Mo(2) atom. In the fifth O site, O(5) is bonded in a 5-coordinate geometry to one Mg(1), two equivalent Ho(1), one Mo(1), and one Mo(2) atom. In the sixth O site, O(6) is bonded to one Mg(1), one Ho(1), one Mo(1), and one Mo(2) atom to form distorted corner-sharing OHoMgMo2 trigonal pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
