NbCr2Tc crystallizes in the orthorhombic Immm space group. The structure is one-dimensional and consists of two NbCr2Tc ribbons oriented in the (1, 0, 0) direction. Nb is bonded in a linear geometry to two equivalent Cr atoms. Both Nb–Cr bond lengths are 2.34 Å. Cr is bonded in a linear geometry to one Nb and one Tc atom. The Cr–Tc bond length is 2.32 Å. Tc is bonded in a linear geometry to two equivalent Cr atoms.
