TmCl2 is Baddeleyite-like structured and crystallizes in the orthorhombic Pbca space group. Tm(1) is bonded to three equivalent Cl(2) and four equivalent Cl(1) atoms to form a mixture of distorted corner and edge-sharing TmCl7 pentagonal bipyramids. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded to four equivalent Tm(1) atoms to form a mixture of distorted corner and edge-sharing ClTm4 tetrahedra. In the second Cl site, Cl(2) is bonded in a trigonal planar geometry to three equivalent Tm(1) atoms.
