Sc Sc Cr Ag
Sc2CrAg crystallizes in the monoclinic Cm space group. Sc(1) is bonded in a 2-coordinate geometry to four equivalent Cr(1) and two equivalent Ag(1) atoms. There are a spread of Sc(1)-Cr(1) bond distances ranging from 2.39-3.38 Å. There is one shorter (2.39 Å) and one longer (2.70 Å) Sc(1)-Ag(1) bond length. Cr(1) is bonded in a 9-coordinate geometry to eight equivalent Sc(1) and one Ag(1) atom. The Cr(1)-Ag(1) bond length is 2.81 Å. Ag(1) is bonded in a 4-coordinate geometry to four equivalent Sc(1) and one Cr(1) atom.
