The crystal structure described by Pt4Tb3 crystallizes in the triclinic P-1 space group. There are three inequivalent Tb sites. In the first Tb site, Tb(1) is bonded in a 9-coordinate geometry to one Pt(1), one Pt(2), two equivalent Pt(3), two equivalent Pt(5), and three equivalent Pt(4) atoms. In the second Tb site, Tb(2) is bonded in a 9-coordinate geometry to one Pt(1), one Pt(2), two equivalent Pt(3), two equivalent Pt(4), and three equivalent Pt(5) atoms. In the third Tb site, Tb(3) is bonded in a 9-coordinate geometry to one Pt(1), one Pt(2), two equivalent Pt(4), two equivalent Pt(5), and three equivalent Pt(3) atoms. There are five inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 6-coordinate geometry to two equivalent Tb(1), two equivalent Tb(2), and two equivalent Tb(3) atoms. In the second Pt site, Pt(2) is bonded in a distorted octahedral geometry to two equivalent Tb(1), two equivalent Tb(2), and two equivalent Tb(3) atoms. In the third Pt site, Pt(3) is bonded in a 10-coordinate geometry to two equivalent Tb(1), two equivalent Tb(2), three equivalent Tb(3), one Pt(3), one Pt(4), and one Pt(5) atom. In the fourth Pt site, Pt(4) is bonded in a 10-coordinate geometry to two equivalent Tb(2), two equivalent Tb(3), three equivalent Tb(1), one Pt(3), one Pt(4), and one Pt(5) atom. In the fifth Pt site, Pt(5) is bonded in a 10-coordinate geometry to two equivalent Tb(1), two equivalent Tb(3), three equivalent Tb(2), one Pt(3), one Pt(4), and one Pt(5) atom. is represented by the CIF card [CIF]
