Ga Ga Fe Tc
TcFeGa2 crystallizes in the triclinic P1 space group. Tc(1) is bonded in a single-bond geometry to one Fe(1) and two equivalent Ga(2) atoms. The Tc(1)-Fe(1) bond length is 0.82 Å. There is one shorter (2.46 Å) and one longer (3.28 Å) Tc(1)-Ga(2) bond length. Fe(1) is bonded in a distorted water-like geometry to one Tc(1), one Ga(1), and one Ga(2) atom. The Fe(1)-Ga(1) bond length is 0.95 Å. The Fe(1)-Ga(2) bond length is 2.21 Å. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a single-bond geometry to one Fe(1) and two equivalent Ga(2) atoms. There is one shorter (2.31 Å) and one longer (2.32 Å) Ga(1)-Ga(2) bond length. In the second Ga site, Ga(2) is bonded in a 7-coordinate geometry to two equivalent Tc(1), one Fe(1), two equivalent Ga(1), and two equivalent Ga(2) atoms. Both Ga(2)-Ga(2) bond lengths are 2.84 Å.
