Sc2ZrTl crystallizes in the orthorhombic Immm space group. The structure is one-dimensional and consists of two Sc2ZrTl ribbons oriented in the (1, 0, 0) direction. Sc is bonded in a linear geometry to one Zr and one Tl atom. The Sc–Zr bond length is 2.48 Å. The Sc–Tl bond length is 2.93 Å. Zr is bonded in a linear geometry to two equivalent Sc atoms. Tl is bonded in a linear geometry to two equivalent Sc atoms.
