Si B Pt
PtBSi crystallizes in the trigonal R3m space group. Pt(1) is bonded to four equivalent B(1) and three equivalent Si(1) atoms to form PtSi3B4 hexagonal pyramids that share corners with three equivalent B(1)Si3Pt4 hexagonal pyramids, corners with six equivalent Pt(1)Si3B4 hexagonal pyramids, edges with three equivalent B(1)Si3Pt4 hexagonal pyramids, and edges with six equivalent Pt(1)Si3B4 hexagonal pyramids. There are three shorter (2.29 Å) and one longer (2.60 Å) Pt(1)-B(1) bond length. All Pt(1)-Si(1) bond lengths are 2.24 Å. B(1) is bonded to four equivalent Pt(1) and three equivalent Si(1) atoms to form BSi3Pt4 hexagonal pyramids that share corners with three equivalent Pt(1)Si3B4 hexagonal pyramids, corners with six equivalent B(1)Si3Pt4 hexagonal pyramids, edges with three equivalent Pt(1)Si3B4 hexagonal pyramids, and edges with six equivalent B(1)Si3Pt4 hexagonal pyramids. All B(1)-Si(1) bond lengths are 2.24 Å. Si(1) is bonded in a hexagonal planar geometry to three equivalent Pt(1) and three equivalent B(1) atoms.
