Y Cr Cr Ag
YCr2Ag crystallizes in the monoclinic Cm space group. Y(1) is bonded in a distorted linear geometry to one Cr(1) and one Cr(2) atom. The Y(1)-Cr(1) bond length is 0.98 Å. The Y(1)-Cr(2) bond length is 1.78 Å. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a single-bond geometry to one Y(1) and one Ag(1) atom. The Cr(1)-Ag(1) bond length is 3.51 Å. In the second Cr site, Cr(2) is bonded in a single-bond geometry to one Y(1) and one Ag(1) atom. The Cr(2)-Ag(1) bond length is 3.51 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded to one Cr(1); one Cr(2); and six Ag(1,1) atoms to form a mixture of corner and edge-sharing AgCr2Ag6 hexagonal bipyramids. All Ag(1)-Ag(1,1) bond lengths are 2.84 Å. In the second Ag site, Ag(1) is bonded to one Cr(1); one Cr(2); and six Ag(1,1) atoms to form a mixture of corner and edge-sharing AgCr2Ag6 hexagonal bipyramids. The Ag(1)-Cr(1) bond length is 3.51 Å. The Ag(1)-Cr(2) bond length is 3.51 Å. Both Ag(1)-Ag(1) bond lengths are 2.84 Å.
