Phenylamines as building blocks to layered inorganic–organic structures

Abstract

Five inorganic–organic layered composites have been prepared and characterised. Copper(II) chloride and lead(II) chloride compounds with 1,4-phenylenediamine and benzidine have a 1∶1 inorganic∶organic layer structure. The copper(II) chloride structure with p-biphenylamine is a 1∶2 inorganic∶organic layer structure; this compound undergoes an order–disorder transition at ca. 200 K. Crystallisation of benzidine in the presence of lead (II) chloride or cobalt(II) chloride at elevated temperature produced the chloride salt of benzidine.
