Single crystal growth of lead (II) n-octa-, n-nona- and n-decanoate

Abstract

Single crystals of lead (II) n-octa (Pb(C8)2), n-nona (Pb(C9)2), and n-decanoate (Pb(C10)2) have been obtained by using a silica gel technique. These crystals have been identified by polarizing light microscopy, X-ray diffraction, Raman spectroscopy, and scanning electron microscopy. The crystals show polyhedral morphology bounded by flat (001) faces and non-flat striated faces. Cleavage lines can be observed in the (001) faces. This cleavage can be related with the bilayer structure of these compounds. Two kinds of crystals with different internal cleavage angle have been found in Pb(C9)2 and Pb(C10)2. The value of this angle is 90° in one of them and 120° in the other one. This fact can be explained by taking into account the polymorphism and polytypism in the lead (II) alkanoates series.
