The Crystal Structure Of Lead Nitrate

2022-01-03

The crystal structure of lead Nitrate has been determined by neutron diffraction. The lead atoms are piled up in the form of face-centered cubic in the cubic crystal system. Its space group is Pa3Z=4 (Braffe lattice notation), and the side length of each unit cell is 784pm.

In this figure, the black dots represent lead atoms, the white dots represent nitrate ions that are 27 pm higher than the lead atomic plane, and the blue dots represent nitrate ions that are 27 pm lower than the lead atomic plane. In this state, each lead atom is bonded with 12 oxygen atoms, and the bond lengths of all N–O bonds in the crystal are the same, all of which are 127pm.

I was interested in the crystal structure of lead nitrate before to study it, part of the reason is that the nitrate ions inside the crystal lattice may be able to rotate freely at high temperatures, but this prediction was not confirmed in the end.

use
Glass lining industry is used to make milk yellow pigment. The paper industry is used as the yellow pigment of paper. Used as a mordant in the printing and dyeing industry. In the inorganic industry, it is used in the manufacture of other lead salts and lead dioxide. The pharmaceutical industry is used to manufacture astringents and so on. Benzene industry is used as a tanning agent. The photographic industry is used as a photo sensitizer. Used in the mining industry as an ore flotation agent. In addition, it is also used as an oxidant for the production of matches, fireworks, explosives, and analytical chemical reagents.
