The compound described by Eu2Mo2O7 crystallizes in the cubic Fd-3m space group. Eu(1) is bonded to two equivalent O(1) and six equivalent O(2) atoms to form distorted EuO8 hexagonal bipyramids that share edges with six equivalent Eu(1)O8 hexagonal bipyramids and edges with six equivalent Mo(1)O6 octahedra. Mo(1) is bonded to six equivalent O(2) atoms to form MoO6 octahedra that share corners with six equivalent Mo(1)O6 octahedra and edges with six equivalent Eu(1)O8 hexagonal bipyramids. The corner-sharing octahedral tilt angles are 43°. There are two inequivalent O sites. In the first O site, O(1) is bonded to four equivalent Eu(1) atoms to form corner-sharing OEu4 tetrahedra. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Eu(1) and two equivalent Mo(1) atoms. is represented by the CIF card [CIF]
