In the second Yb site, Yb(2) is bonded in a 14-coordinate geometry to four equivalent Pt(1), two equivalent Ge(2), four equivalent Ge(1), and four equivalent Ge(3) atoms. Pt(1) is bonded in a 10-coordinate geometry to two equivalent Yb(2), three equivalent Yb(1), one Ge(1), one Ge(3), and three equivalent Ge(2) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to two equivalent Yb(1), four equivalent Yb(2), two equivalent Pt(1), and one Ge(1) atom. In the second Ge site, Ge(2) is bonded in a 8-coordinate geometry to one Yb(2), three equivalent Yb(1), three equivalent Pt(1), and one Ge(2) atom. In the third Ge site, Ge(3) is bonded in a 2-coordinate geometry to one Yb(1), four equivalent Yb(2), and two equivalent Pt(1) atoms.
