The material described by MgHo2Mo2(O4Cl)2 crystallizes in the monoclinic Cm space group. Mg(1) is bonded in a 6-coordinate geometry to one O(1), one O(6), two equivalent O(3), and two equivalent O(5) atoms. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 8-coordinate geometry to one O(4), one O(6), two equivalent O(3), two equivalent O(5), one Cl(1), and one Cl(2) atom. In the second Ho site, Ho(2) is bonded in a 6-coordinate geometry to one O(2), two equivalent O(3), two equivalent O(5), one Cl(1), and one Cl(2) atom. There are two inequivalent Mo sites. In the first Mo site, Mo(1) is bonded in a 5-coordinate geometry to one O(1), one O(2), one O(6), and two equivalent O(3) atoms. In the second Mo site, Mo(2) is bonded in a distorted rectangular see-saw-like geometry to one O(1), one O(4), two equivalent O(5), and one Cl(1) atom. There are six inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Mg(1), one Mo(1), and one Mo(2) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Ho(2) and one Mo(1) atom. In the third O site, O(3) is bonded to one Mg(1), one Ho(1), one Ho(2), and one Mo(1) atom to form a mixture of distorted corner and face-sharing OHo2MgMo trigonal pyramids. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to one Ho(1) and one Mo(2) atom. In the fifth O site, O(5) is bonded in a rectangular see-saw-like geometry to one Mg(1), one Ho(1), one Ho(2), and one Mo(2) atom. In the sixth O site, O(6) is bonded in a T-shaped geometry to one Mg(1), one Ho(1), and one Mo(1) atom. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a 3-coordinate geometry to one Ho(1), one Ho(2), and one Mo(2) atom. In the second Cl site, Cl(2) is bonded in a water-like geometry to one Ho(1) and one Ho(2) atom. is represented by the CIF card [CIF]
