Sr Ir Ru Ru
SrRu2Ir is beta Plutonium-derived structured and crystallizes in the triclinic P1 space group. Sr(1) is bonded in a 8-coordinate geometry to four equivalent Ru(1), four equivalent Ru(2), and four equivalent Ir(1) atoms. There are a spread of Sr(1)-Ru(1) bond distances ranging from 2.48-3.19 Å. There are a spread of Sr(1)-Ru(2) bond distances ranging from 3.07-3.85 Å. There are a spread of Sr(1)-Ir(1) bond distances ranging from 2.64-3.08 Å. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a 2-coordinate geometry to four equivalent Sr(1) and four equivalent Ru(2) atoms. There are a spread of Ru(1)-Ru(2) bond distances ranging from 2.64-3.08 Å. In the second Ru site, Ru(2) is bonded in a 14-coordinate geometry to four equivalent Sr(1), two equivalent Ru(2), four equivalent Ru(1), and four equivalent Ir(1) atoms. Both Ru(2)-Ru(2) bond lengths are 2.93 Å. There are a spread of Ru(2)-Ir(1) bond distances ranging from 2.48-3.19 Å. Ir(1) is bonded in a 6-coordinate geometry to four equivalent Sr(1) and four equivalent Ru(2) atoms.
