Be P P Pb
BePbP2 crystallizes in the triclinic P1 space group. Be(1) is bonded in a distorted single-bond geometry to two equivalent Pb(1), one P(1), and one P(2) atom. There is one shorter (2.43 Å) and one longer (2.74 Å) Be(1)-Pb(1) bond length. The Be(1)-P(1) bond length is 2.57 Å. The Be(1)-P(2) bond length is 1.56 Å. Pb(1) is bonded in a 4-coordinate geometry to two equivalent Be(1) and two equivalent P(1) atoms. There is one shorter (2.13 Å) and one longer (2.26 Å) Pb(1)-P(1) bond length. There are two inequivalent P sites. In the first P site, P(1) is bonded in a 4-coordinate geometry to one Be(1), two equivalent Pb(1), and one P(2) atom. The P(1)-P(2) bond length is 2.36 Å. In the second P site, P(2) is bonded in a distorted single-bond geometry to one Be(1) and one P(1) atom.
