Materials Data on MoPt3 by Materials Project

Pt3Mo1 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Mo6+ is bonded to twelve equivalent Pt2- atoms to form MoPt12 cuboctahedra that share corners with twelve equivalent MoPt12 cuboctahedra, edges with twenty-four equivalent PtMo4Pt8 cuboctahedra, faces with six equivalent MoPt12 cuboctahedra, and faces with twelve equivalent PtMo4Pt8 cuboctahedra. All Mo–Pt bond lengths are 2.81 Å. Pt2- is bonded to four equivalent Mo6+ and eight equivalent Pt2- atoms to form PtMo4Pt8 cuboctahedra that share corners with twelve equivalent PtMo4Pt8 cuboctahedra, edges with eight equivalent MoPt12 cuboctahedra, edges with sixteen equivalent PtMo4Pt8 cuboctahedra, faces with four equivalent MoPt12 cuboctahedra, and faces with fourteen equivalent PtMo4Pt8 cuboctahedra. All Pt–Pt bond lengths are 2.81 Å.

Materials Data on MoPt3 by Materials Project

Pt3Mo1 crystallizes in the orthorhombic Pmm2 space group. The structure is three-dimensional. Mo6+ is bonded in a distorted q6 geometry to ten Pt2- atoms. There are a spread of Mo–Pt bond distances ranging from 2.74–2.83 Å. There are three inequivalent Pt2- sites. In the first Pt2- site, Pt2- is bonded to four equivalent Mo6+ and eight Pt2- atoms to form a mixture of edge, corner, and face-sharing PtMo4Pt8 cuboctahedra. There are a spread of Pt–Pt bond distances ranging from 2.76–2.86 Å. In the second Pt2- site, Pt2- is bonded to four equivalent Mo6+ and eight Pt2- atoms to form a mixture of edge, corner, and face-sharing PtMo4Pt8 cuboctahedra. There are two shorter (2.79 Å) and four longer (2.83 Å) Pt–Pt bond lengths. In the third Pt2- site, Pt2- is bonded to two equivalent Mo6+ and ten Pt2- atoms to form a mixture of edge, corner, and face-sharing PtMo2Pt10 cuboctahedra. Both Pt–Pt bond lengths are 2.79 Å.
