Y Y Y Y Ag
Y4Ag crystallizes in the triclinic P1 space group. There are four inequivalent Y sites. In the first Y site, Y(1) is bonded in a 2-coordinate geometry to one Y(3) and two equivalent Ag(1) atoms. The Y(1)-Y(3) bond length is 2.04 Å. There is one shorter (3.17 Å) and one longer (3.96 Å) Y(1)-Ag(1) bond length. In the second Y site, Y(2) is bonded in a 1-coordinate geometry to one Y(3), one Y(4), and two equivalent Ag(1) atoms. The Y(2)-Y(3) bond length is 2.50 Å. The Y(2)-Y(4) bond length is 2.04 Å. There is one shorter (3.30 Å) and one longer (3.67 Å) Y(2)-Ag(1) bond length. In the third Y site, Y(3) is bonded in a 4-coordinate geometry to one Y(1), one Y(2), and three equivalent Ag(1) atoms. There are a spread of Y(3)-Ag(1) bond distances ranging from 3.11-3.64 Å. In the fourth Y site, Y(4) is bonded in a 3-coordinate geometry to one Y(2) and three equivalent Ag(1) atoms. There are a spread of Y(4)-Ag(1) bond distances ranging from 3.14-3.52 Å. Ag(1) is bonded in a 10-coordinate geometry to two equivalent Y(1), two equivalent Y(2), three equivalent Y(3), and three equivalent Y(4) atoms.
