TcInAl2 crystallizes in the monoclinic Cm space group. Tc(1) is bonded in a distorted single-bond geometry to one In(1) and three equivalent Al(1) atoms. The Tc(1)-In(1) bond length is 0.38 Å. There is one shorter (2.18 Å) and two longer (2.97 Å) Tc(1)-Al(1) bond lengths. In(1) is bonded in a single-bond geometry to one Tc(1) and three equivalent Al(2) atoms. There is one shorter (2.46 Å) and two longer (3.19 Å) In(1)-Al(2) bond lengths. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a 4-coordinate geometry to three equivalent Tc(1) and one Al(2) atom. The Al(1)-Al(2) bond length is 1.98 Å. In the second Al site, Al(2) is bonded in a 4-coordinate geometry to three equivalent In(1) and one Al(1) atom.
