Abstract

The salt metathesis reaction between lead(II) salts and potassium chromate in methanolic solution, mediated by the formation of a soluble complex of potassium chromate with a cyclic polyether, affords orthorhombic PbCrO4 rather than the monoclinic modification formed in aqueous solution. When the aqueous metathesis reaction is carried out in the presence of tertiary amines, a lead oxide-rich phase, PbO•PbCrO4 (Pb2CrO5), is selectively formed.

4. Crystallization of inorganic materials through the intermediacy of inorganic coordination complexes has been reported, but is to be distinguished from the use of molecular organic species (e.g., crown ethers) as solubilizing agents. For example, HgI2 may be recrystallized through the intermediacy of HgI3- and/or HgI4 2- from solutions containing excess iodide: Nicolau, I. F., J. Cryst. Growth 48, 51–60 (1980). Similarly, cinnabar (HgS) has been recrystallized from aqueous sulfide solutions:Google Scholar
