Be4NiSi is Hexagonal Laves-derived structured and crystallizes in the cubic F-43m space group. Be(1) is bonded to six equivalent Be(1), three equivalent Ni(1), and three equivalent Si(1) atoms to form a mixture of corner, edge, and face-sharing BeBe6Si3Ni3 cuboctahedra. Ni(1) is bonded in a 16-coordinate geometry to twelve equivalent Be(1) and four equivalent Si(1) atoms. Si(1) is bonded in a 16-coordinate geometry to twelve equivalent Be(1) and four equivalent Ni(1) atoms.
