The structure described by Sr2MgRuNiO6 crystallizes in the orthorhombic Immm space group. Sr(1) is bonded in a 9-coordinate geometry to one Mg(1), four equivalent O(1), and four equivalent O(2) atoms. Mg(1) is bonded in a square co-planar geometry to two equivalent Sr(1) and four equivalent O(1) atoms. Ru(1) is bonded in an octahedral geometry to two equivalent O(2) and four equivalent O(1) atoms. Ni(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Sr(1), one Mg(1), one Ru(1), and one Ni(1) atom to form a mixture of distorted edge, face, and corner-sharing OSr2MgNiRu trigonal bipyramids. In the second O site, O(2) is bonded in a 5-coordinate geometry to four equivalent Sr(1) and one Ru(1) atom. is represented by the CIF file [CIF]
