The structure described by Y3Pt4Ge13 crystallizes in the trigonal R3c space group. Y(1) is bonded in a 16-coordinate geometry to one Pt(1), three equivalent Pt(2), three equivalent Ge(2), three equivalent Ge(3), three equivalent Ge(4), and three equivalent Ge(5) atoms. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 9-coordinate geometry to three equivalent Y(1), three equivalent Ge(2), and three equivalent Ge(3) atoms. In the second Pt site, Pt(2) is bonded in a 9-coordinate geometry to three equivalent Y(1), one Ge(2), one Ge(3), two equivalent Ge(4), and two equivalent Ge(5) atoms. There are five inequivalent Ge sites. In the first Ge site, Ge(4) is bonded in a 8-coordinate geometry to three equivalent Y(1), two equivalent Pt(2), one Ge(2), and two equivalent Ge(3) atoms. In the second Ge site, Ge(5) is bonded in a 2-coordinate geometry to three equivalent Y(1), two equivalent Pt(2), one Ge(1), and one Ge(2) atom. In the third Ge site, Ge(1) is bonded in a 6-coordinate geometry to three equivalent Ge(3) and three equivalent Ge(5) atoms. In the fourth Ge site, Ge(2) is bonded in a 7-coordinate geometry to three equivalent Y(1), one Pt(1), one Pt(2), one Ge(4), and one Ge(5) atom. In the fifth Ge site, Ge(3) is bonded in a 2-coordinate geometry to three equivalent Y(1), one Pt(1), one Pt(2), one Ge(1), and two equivalent Ge(4) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
