Zr2TcRu crystallizes in the orthorhombic Immm space group. The structure is one-dimensional and consists of two Zr2TcRu ribbons oriented in the (1, 0, 0) direction. Zr is bonded in a linear geometry to one Tc and one Ru atom. The Zr–Tc bond length is 2.31 Å. The Zr–Ru bond length is 2.29 Å. Tc is bonded in a linear geometry to two equivalent Zr atoms. Ru is bonded in a linear geometry to two equivalent Zr atoms.
Zr2TcRu is Heusler structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Zr is bonded in a body-centered cubic geometry to four equivalent Tc and four equivalent Ru atoms. All Zr–Tc bond lengths are 2.85 Å. All Zr–Ru bond lengths are 2.85 Å. Tc is bonded in a body-centered cubic geometry to eight equivalent Zr atoms. Ru is bonded in a body-centered cubic geometry to eight equivalent Zr atoms.
