ScZr2Tc crystallizes in the orthorhombic Immm space group. The structure is one-dimensional and consists of two ScZr2Tc ribbons oriented in the (1, 0, 0) direction. Sc is bonded in a linear geometry to two equivalent Zr atoms. Both Sc–Zr bond lengths are 2.89 Å. Zr is bonded in a linear geometry to one Sc and one Tc atom. The Zr–Tc bond length is 2.24 Å. Tc is bonded in a linear geometry to two equivalent Zr atoms.
ScZrTc2 crystallizes in the orthorhombic Immm space group. The structure is one-dimensional and consists of two ScZrTc2 ribbons oriented in the (1, 0, 0) direction. Sc2+ is bonded in a linear geometry to two equivalent Tc3- atoms. Both Sc–Tc bond lengths are 2.44 Å. Zr4+ is bonded in a linear geometry to two equivalent Tc3- atoms. Both Zr–Tc bond lengths are 2.36 Å. Tc3- is bonded in a linear geometry to one Sc2+ and one Zr4+ atom.
