EuPtGe3 crystallizes in the monoclinic Cm space group. Eu(1) is bonded in a single-bond geometry to one Pt(1), one Ge(2), and two equivalent Ge(1) atoms. The Eu(1)-Pt(1) bond length is 2.51 Å. The Eu(1)-Ge(2) bond length is 0.29 Å. Both Eu(1)-Ge(1) bond lengths are 3.13 Å. Pt(1) is bonded in a 3-coordinate geometry to one Eu(1) and two equivalent Ge(1) atoms. Both Pt(1)-Ge(1) bond lengths are 2.00 Å. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 4-coordinate geometry to one Eu(1), one Pt(1), one Ge(1), and one Ge(2) atom. The Ge(1)-Ge(1) bond length is 1.59 Å. The Ge(1)-Ge(2) bond length is 1.83 Å. In the second Ge site, Ge(2) is bonded in a single-bond geometry to one Eu(1) and two equivalent Ge(1) atoms.
