Be2GeP crystallizes in the triclinic P1 space group. There are two inequivalent Be sites. In the first Be site, Be(1) is bonded in a 2-coordinate geometry to one Be(2), one Ge(1), and one P(1) atom. The Be(1)-Be(2) bond length is 0.68 Å. The Be(1)-Ge(1) bond length is 2.39 Å. The Be(1)-P(1) bond length is 1.85 Å. In the second Be site, Be(2) is bonded in a 4-coordinate geometry to one Be(1), two equivalent Ge(1), and one P(1) atom. There is one shorter (2.36 Å) and one longer (2.42 Å) Be(2)-Ge(1) bond length. The Be(2)-P(1) bond length is 2.53 Å. Ge(1) is bonded in a 5-coordinate geometry to one Be(1), two equivalent Be(2), and two equivalent P(1) atoms. There is one shorter (1.89 Å) and one longer (2.17 Å) Ge(1)-P(1) bond length. P(1) is bonded in a 4-coordinate geometry to one Be(1), one Be(2), and two equivalent Ge(1) atoms.
