BeAg2P is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two BeAg2P clusters. Be(1) is bonded in a 3-coordinate geometry to two equivalent Ag(1) and one P(1) atom. Both Be(1)-Ag(1) bond lengths are 0.18 Å. The Be(1)-P(1) bond length is 0.17 Å. Ag(1) is bonded in a 3-coordinate geometry to one Be(1), one Ag(1), and one P(1) atom. The Ag(1)-Ag(1) bond length is 0.17 Å. The Ag(1)-P(1) bond length is 0.18 Å. P(1) is bonded in a 3-coordinate geometry to one Be(1) and two equivalent Ag(1) atoms.
