Materials Data on LaGa2Pt3 by Materials Project
LaPt3Ga2 crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. La2+ is bonded to twelve equivalent Pt2- atoms to form a mixture of edge, face, and corner-sharing LaPt12 cuboctahedra. All La–Pt bond lengths are 3.48 Å. Pt2- is bonded in a 12-coordinate geometry to four equivalent La2+ and four equivalent Ga2+ atoms. All Pt–Ga bond lengths are 2.61 Å. Ga2+ is bonded in a 6-coordinate geometry to six equivalent Pt2- atoms.
