(RuTe8Cl)2Cl2 crystallizes in the monoclinic C2/c space group. The structure consists of four hydrochloric acid atoms inside a RuTe8Cl framework. In the RuTe8Cl framework, Ru(1) is bonded in an octahedral geometry to two equivalent Te(1), two equivalent Te(2), and two equivalent Te(3) atoms. There are four inequivalent Te sites. In the first Te site, Te(1) is bonded in a 4-coordinate geometry to one Ru(1), one Te(1), one Te(4), and one Cl(2) atom. In the second Te site, Te(2) is bonded in a 3-coordinate geometry to one Ru(1), one Te(2), and one Te(3) atom. In the third Te site, Te(3) is bonded in a 3-coordinate geometry to one Ru(1), one Te(2), and one Te(4) atom. In the fourth Te site, Te(4) is bonded in an L-shaped geometry to one Te(1) and one Te(3) atom. Cl(2) is bonded in a linear geometry to two equivalent Te(1) atoms.
