LuPt3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Lu is bonded to twelve equivalent Pt atoms to form a mixture of face and corner-sharing LuPt12 cuboctahedra. All Lu–Pt bond lengths are 2.88 Å. Pt is bonded in a distorted square co-planar geometry to four equivalent Lu atoms.
LuPt crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Lu is bonded in a 7-coordinate geometry to seven equivalent Pt atoms. There are a spread of Lu–Pt bond distances ranging from 2.83–3.01 Å. Pt is bonded in a 7-coordinate geometry to seven equivalent Lu atoms.
Lu3Pt4 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Lu is bonded in a 9-coordinate geometry to nine Pt atoms. There are a spread of Lu–Pt bond distances ranging from 2.82–3.24 Å. There are three inequivalent Pt sites. In the first Pt site, Pt is bonded in a 6-coordinate geometry to six equivalent Lu atoms. In the second Pt site, Pt is bonded in a distorted octahedral geometry to six equivalent Lu atoms. In the third Pt site, Pt is bonded in a 10-coordinate geometry to seven equivalent Lu and three equivalent Pt atoms. There are one shorter (2.88 Å) and two longer (2.94 Å) Pt–Pt bond lengths.
Lu2Pt is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Lu sites. In the first Lu site, Lu is bonded to four equivalent Pt atoms to form a mixture of edge and corner-sharing LuPt4 tetrahedra. There are a spread of Lu–Pt bond distances ranging from 2.83–2.90 Å. In the second Lu site, Lu is bonded in a 3-coordinate geometry to three equivalent Pt atoms. There are one shorter (2.79 Å) and two longer (3.01 Å) Lu–Pt bond lengths. Pt is bonded in a 7-coordinate geometry to seven Lu atoms.
Lu3Pt is Cementite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Lu sites. In the first Lu site, Lu is bonded in a 2-coordinate geometry to three equivalent Pt atoms. There are a spread of Lu–Pt bond distances ranging from 2.81–3.29 Å. In the second Lu site, Lu is bonded in a distorted bent 120 degrees geometry to two equivalent Pt atoms. There are one shorter (2.74 Å) and one longer (2.81 Å) Lu–Pt bond lengths. Pt is bonded in a 6-coordinate geometry to eight Lu atoms.
