Y Y Y Y V
Y4V crystallizes in the triclinic P1 space group. There are four inequivalent Y sites. In the first Y site, Y(1) is bonded in a 5-coordinate geometry to one Y(2), two equivalent Y(3), and two equivalent V(1) atoms. The Y(1)-Y(2) bond length is 2.48 Å. There is one shorter (2.78 Å) and one longer (3.14 Å) Y(1)-Y(3) bond length. There is one shorter (3.04 Å) and one longer (3.20 Å) Y(1)-V(1) bond length. In the second Y site, Y(2) is bonded in a 2-coordinate geometry to one Y(1) and two equivalent V(1) atoms. There is one shorter (2.47 Å) and one longer (2.72 Å) Y(2)-V(1) bond length. In the third Y site, Y(3) is bonded in a 4-coordinate geometry to one Y(4), two equivalent Y(1), and one V(1) atom. The Y(3)-Y(4) bond length is 2.46 Å. The Y(3)-V(1) bond length is 3.45 Å. In the fourth Y site, Y(4) is bonded in a 1-coordinate geometry to one Y(3) and two equivalent V(1) atoms. There is one shorter (2.72 Å) and one longer (3.22 Å) Y(4)-V(1) bond length. V(1) is bonded in a 7-coordinate geometry to one Y(3), two equivalent Y(1), two equivalent Y(2), and two equivalent Y(4) atoms.
