The compound described by PbP7 crystallizes in the monoclinic P2_1/c space group. Pb(1) is bonded in a 3-coordinate geometry to one P(1), one P(4), and two equivalent P(6) atoms. There are seven inequivalent P sites. In the first P site, P(1) is bonded in a trigonal non-coplanar geometry to one Pb(1), one P(3), and one P(7) atom. In the second P site, P(2) is bonded in a distorted trigonal non-coplanar geometry to one P(3), one P(4), and one P(7) atom. In the third P site, P(3) is bonded in a trigonal non-coplanar geometry to one P(1), one P(2), and one P(4) atom. In the fourth P site, P(4) is bonded in a 4-coordinate geometry to one Pb(1), one P(2), one P(3), and one P(6) atom. In the fifth P site, P(5) is bonded in a distorted T-shaped geometry to one P(5), one P(6), and one P(7) atom. In the sixth P site, P(6) is bonded to two equivalent Pb(1), one P(4), and one P(5) atom to form distorted corner-sharing PP2Pb2 trigonal pyramids. In the seventh P site, P(7) is bonded in a trigonal non-coplanar geometry to one P(1), one P(2), and one P(5) atom. is represented by the CIF card [CIF]
