Ga Tc Ru Ru
TcRu2Ga crystallizes in the monoclinic Cm space group. Tc(1) is bonded in a single-bond geometry to one Ru(1) and four equivalent Ga(1) atoms. The Tc(1)-Ru(1) bond length is 1.74 Å. There are a spread of Tc(1)-Ga(1) bond distances ranging from 2.71-3.03 Å. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a distorted single-bond geometry to one Tc(1) and four equivalent Ru(2) atoms. There are a spread of Ru(1)-Ru(2) bond distances ranging from 1.84-2.28 Å. In the second Ru site, Ru(2) is bonded in a 5-coordinate geometry to four equivalent Ru(1) and one Ga(1) atom. The Ru(2)-Ga(1) bond length is 2.74 Å. Ga(1) is bonded in a 9-coordinate geometry to four equivalent Tc(1), one Ru(2), and four equivalent Ga(1) atoms. All Ga(1)-Ga(1) bond lengths are 2.89 Å.
