The compound described by Ho2V2O7 crystallizes in the monoclinic C2/m space group. Ho(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form distorted edge-sharing HoO6 pentagonal pyramids. V(1) is bonded in a 5-coordinate geometry to one O(3), two equivalent O(1), and two equivalent O(2) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Ho(1) and one V(1) atom. In the second O site, O(2) is bonded to two equivalent Ho(1) and two equivalent V(1) atoms to form distorted edge-sharing OHo2V2 trigonal pyramids. In the third O site, O(3) is bonded in a linear geometry to two equivalent V(1) atoms. is represented by the CIF file [CIF]
