Be2PtNi crystallizes in the monoclinic Pm space group. Be(1) is bonded in a 5-coordinate geometry to one Be(1), two equivalent Pt(1), and two equivalent Ni(1) atoms. The Be(1)-Be(1) bond length is 0.94 Å. There is one shorter (2.27 Å) and one longer (2.65 Å) Be(1)-Pt(1) bond length. There is one shorter (2.27 Å) and one longer (2.65 Å) Be(1)-Ni(1) bond length. Pt(1) is bonded in a distorted single-bond geometry to four equivalent Be(1) and one Ni(1) atom. The Pt(1)-Ni(1) bond length is 1.10 Å. Ni(1) is bonded in a distorted single-bond geometry to four equivalent Be(1) and one Pt(1) atom.
