The compound described by Sr2MgMo2O6 crystallizes in the monoclinic C2/m space group. Sr(1) is bonded in a 5-coordinate geometry to three equivalent O(1) and six equivalent O(2) atoms. Mg(1) is bonded in a distorted square co-planar geometry to two equivalent O(1) and four equivalent O(2) atoms. There are two inequivalent Mo sites. In the first Mo site, Mo(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form distorted corner-sharing MoO6 octahedra. The corner-sharing octahedral tilt angles range from 32-38°. In the second Mo site, Mo(2) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing MoO6 octahedra. The corner-sharing octahedral tilt angles range from 32-38°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 6-coordinate geometry to three equivalent Sr(1), one Mg(1), one Mo(1), and one Mo(2) atom. In the second O site, O(2) is bonded in a 6-coordinate geometry to three equivalent Sr(1), one Mg(1), one Mo(1), and one Mo(2) atom. is represented by the CIF card [CIF]
