WebABSTRACT. In this paper we report the synthesis and the crystal structure of eight inorganic-organic hybrids containing various lead halides as the inorganic motif and a chiral, primary ammonium cation as the organic constituent. The organic cation investigated is (C 6 H 11 C*H (CH 3 )NH 3 )+ and both the ( R) and ( S) as well as the racemic ...
