Yb2PtGe6 crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are two inequivalent Yb sites. In the first Yb site, Yb is bonded in a 10-coordinate geometry to ten Ge atoms. There are a spread of Yb–Ge bond distances ranging from 3.07–3.30 Å. In the second Yb site, Yb is bonded in a 8-coordinate geometry to four equivalent Pt and ten Ge atoms. All Yb–Pt bond lengths are 3.14 Å. There are a spread of Yb–Ge bond distances ranging from 3.15–3.50 Å. Pt is bonded in a 9-coordinate geometry to four equivalent Yb and five Ge atoms. There are a spread of Pt–Ge bond distances ranging from 2.44–2.57 Å. There are six inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to two equivalent Yb, two equivalent Pt, and five Ge atoms. There are one shorter (2.48 Å) and four longer (2.90 Å) Ge–Ge bond lengths. In the second Ge site, Ge is bonded in a 7-coordinate geometry to two equivalent Yb and five Ge atoms. All Ge–Ge bond lengths are 2.90 Å. In the third Ge site, Ge is bonded in a 6-coordinate geometry to six Yb and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.47 Å. In the fourth Ge site, Ge is bonded in a 1-coordinate geometry to six Yb, one Pt, and two equivalent Ge atoms. In the fifth Ge site, Ge is bonded in a 7-coordinate geometry to two equivalent Yb and five Ge atoms. The Ge–Ge bond length is 2.48 Å. In the sixth Ge site, Ge is bonded in a 2-coordinate geometry to two equivalent Yb, two equivalent Pt, and five Ge atoms.
