Mo(SeCl6)2 is Indium-like structured and crystallizes in the orthorhombic Fdd2 space group. The structure is zero-dimensional and consists of eight Mo(SeCl6)2 clusters. Mo(1) is bonded in an octahedral geometry to two equivalent Cl(1), two equivalent Cl(2), and two equivalent Cl(3) atoms. Se(1) is bonded in a 5-coordinate geometry to one Cl(2), one Cl(3), one Cl(4), one Cl(5), and one Cl(6) atom. There are six inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a single-bond geometry to one Mo(1) atom. In the second Cl site, Cl(2) is bonded in a distorted water-like geometry to one Mo(1) and one Se(1) atom. In the third Cl site, Cl(3) is bonded in a water-like geometry to one Mo(1) and one Se(1) atom. In the fourth Cl site, Cl(4) is bonded in a single-bond geometry to one Se(1) atom. In the fifth Cl site, Cl(5) is bonded in a single-bond geometry to one Se(1) atom. In the sixth Cl site, Cl(6) is bonded in a single-bond geometry to one Se(1) atom.
