Pb5P is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Pb5P clusters. There are five inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a distorted bent 150 degrees geometry to one Pb(5) and one P(1) atom. The Pb(1)-Pb(5) bond length is 1.54 Å. The Pb(1)-P(1) bond length is 1.74 Å. In the second Pb site, Pb(2) is bonded in a single-bond geometry to one Pb(5) atom. The Pb(2)-Pb(5) bond length is 1.54 Å. In the third Pb site, Pb(3) is bonded in a distorted linear geometry to one Pb(4) and one P(1) atom. The Pb(3)-Pb(4) bond length is 2.66 Å. The Pb(3)-P(1) bond length is 2.50 Å. In the fourth Pb site, Pb(4) is bonded in a distorted single-bond geometry to one Pb(3) atom. In the fifth Pb site, Pb(5) is bonded in a linear geometry to one Pb(1) and one Pb(2) atom. P(1) is bonded in a distorted bent 150 degrees geometry to one Pb(1) and one Pb(3) atom.
