The crystal structure described by MgTm2V2O8 crystallizes in the monoclinic C2 space group. Mg(1) is bonded in a 4-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. There are two inequivalent Tm sites. In the first Tm site, Tm(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. In the second Tm site, Tm(2) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. There are two inequivalent V sites. In the first V site, V(1) is bonded in a distorted trigonal pyramidal geometry to two equivalent O(2) and two equivalent O(3) atoms. In the second V site, V(2) is bonded in a tetrahedral geometry to two equivalent O(1) and two equivalent O(4) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Mg(1), one Tm(1), one Tm(2), and one V(2) atom. In the second O site, O(2) is bonded in a distorted see-saw-like geometry to one Mg(1), one Tm(1), one Tm(2), and one V(1) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to one Mg(1), one Tm(1), one Tm(2), and one V(1) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Tm(1), one Tm(2), and one V(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
