Sr Tc Tc Ni
SrTc2Ni crystallizes in the monoclinic Cm space group. Sr(1) is bonded in a 12-coordinate geometry to four equivalent Sr(1), four equivalent Tc(1), and four equivalent Tc(2) atoms. All Sr(1)-Sr(1) bond lengths are 2.74 Å. There are a spread of Sr(1)-Tc(1) bond distances ranging from 3.13-3.70 Å. There are a spread of Sr(1)-Tc(2) bond distances ranging from 3.13-3.70 Å. There are two inequivalent Tc sites. In the first Tc site, Tc(1) is bonded in a 1-coordinate geometry to four equivalent Sr(1) and one Ni(1) atom. The Tc(1)-Ni(1) bond length is 1.87 Å. In the second Tc site, Tc(2) is bonded in a 12-coordinate geometry to four equivalent Sr(1), four equivalent Tc(2), and four equivalent Ni(1) atoms. All Tc(2)-Tc(2) bond lengths are 2.74 Å. There are a spread of Tc(2)-Ni(1) bond distances ranging from 2.55-3.23 Å. Ni(1) is bonded in a 1-coordinate geometry to one Tc(1) and four equivalent Tc(2) atoms.
