NbMo2Tc crystallizes in the orthorhombic Immm space group. The structure is one-dimensional and consists of two NbMo2Tc ribbons oriented in the (1, 0, 0) direction. Nb is bonded in a linear geometry to two equivalent Mo atoms. Both Nb–Mo bond lengths are 2.31 Å. Mo is bonded in a linear geometry to one Nb and one Tc atom. The Mo–Tc bond length is 2.25 Å. Tc is bonded in a linear geometry to two equivalent Mo atoms.
NbMoTc2 crystallizes in the orthorhombic Immm space group. The structure is one-dimensional and consists of two NbMoTc2 ribbons oriented in the (1, 0, 0) direction. Nb4+ is bonded in a linear geometry to two equivalent Tc3- atoms. Both Nb–Tc bond lengths are 2.26 Å. Mo2+ is bonded in a linear geometry to two equivalent Tc3- atoms. Both Mo–Tc bond lengths are 2.25 Å. Tc3- is bonded in a linear geometry to one Nb4+ and one Mo2+ atom.
