Chemical compound

Lead heptaphosphide is the only binary phosphide currently known to be formed by lead and phosphorus. The chemical formula is PbP7, which contains atom clusters. This compound is stable in the air.

Preparation

Lead heptaphosphide can be produced by the reaction of red phosphorus and lead:

7 P4 + 4 Pb → 4 PbP7

It decomposes again into the elements at 550 K (277 °C).

Properties

Lead heptaphosphide crystallises in the monoclinic crystal system, with space group P21/c, a=970.70(11), b=673.34(10), c=1243.89(18) pm and β=122.55(1)°. Each phosphorus atom in the phosphorus cluster is connected to the other six.
