Ga Tc Rh Rh
TcRh2Ga crystallizes in the monoclinic Cm space group. Tc(1) is bonded in a 1-coordinate geometry to four equivalent Rh(2) and three equivalent Ga(1) atoms. There are a spread of Tc(1)-Rh(2) bond distances ranging from 2.74-3.17 Å. There is one shorter (2.05 Å) and two longer (2.34 Å) Tc(1)-Ga(1) bond lengths. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 5-coordinate geometry to four equivalent Rh(2) and one Ga(1) atom. There are a spread of Rh(1)-Rh(2) bond distances ranging from 1.99-2.56 Å. The Rh(1)-Ga(1) bond length is 3.24 Å. In the second Rh site, Rh(2) is bonded in a 8-coordinate geometry to four equivalent Tc(1) and four equivalent Rh(1) atoms. Ga(1) is bonded in a 3-coordinate geometry to three equivalent Tc(1) and one Rh(1) atom.
