(Mg(H2O)6)2CdBr6 is Indium-derived structured and crystallizes in the trigonal R-3 space group. The structure is zero-dimensional and consists of three CdBr6 clusters and six Mg(H2O)6 clusters. In each CdBr6 cluster, Cd(1) is bonded in an octahedral geometry to six equivalent Br(1) atoms. Br(1) is bonded in a distorted single-bond geometry to one Cd(1) atom. In each Mg(H2O)6 cluster, Mg(1) is bonded in an octahedral geometry to three equivalent O(1) and three equivalent O(2) atoms. There are four inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(1) atom. In the third H site, H(3) is bonded in a single-bond geometry to one O(2) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one O(2) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Mg(1), one H(1), and one H(2) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Mg(1), one H(3), and one H(4) atom.
