Ga P P Pb
GaPbP2 is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two GaPbP2 clusters. Ga(1) is bonded in a 2-coordinate geometry to one Pb(1) and one P(1) atom. The Ga(1)-Pb(1) bond length is 1.09 Å. The Ga(1)-P(1) bond length is 1.16 Å. Pb(1) is bonded in a 3-coordinate geometry to one Ga(1), one P(1), and one P(2) atom. The Pb(1)-P(1) bond length is 1.04 Å. The Pb(1)-P(2) bond length is 1.04 Å. There are two inequivalent P sites. In the first P site, P(1) is bonded in a 3-coordinate geometry to one Ga(1), one Pb(1), and one P(2) atom. The P(1)-P(2) bond length is 0.84 Å. In the second P site, P(2) is bonded in a 2-coordinate geometry to one Pb(1) and one P(1) atom.
