Two　new　organically　templated　lead(ii)　iodide　complexes,　[(nbq)(PbI　3)]n　1　and　{[(CH3)3NC　2H4N(CH3)3]3(Pb　6I18)}n　2,　have　been　synthesized　in　the　presence　of　aromatic　and　aliphatic　quaternary　ammonium　compounds,　N-(n-butyl)quinolinium　(nbq+)　and　[(CH3)　3NC2H4N(CH3)3]　2+,　respectively,　acting　as　structure-directing　agents.　Both　1　and　2　consist　of　uncoordinated　structure-directing　agents　and　inorganic　moieties　bound　to　the　organic　structure-directing　agents.　In　1,　an　inorganic　(PbI　3?)n　one-dimensional　polyanion　chain　is　built　up　by　face-sharing　of　distorted　PbI6　tetrahedra.　The　inorganic　framework　of　2　presents　a　two-dimensional　arrangement　that　could　be　discussed　in　terms　of　[Pb3I10]4?　building　blocks.　Static　attractive　interactions　between　organic　countercations　and　inorganic　moieties　were　revealed　through　the　crystal　packing.　Density　functional　theory　calculations　indicate　that　1　possesses　semiconductor　properties,　tuned　by　the　?-electrons　of　nbq+.　In　contrast,　2　is　conductive　in　the　direction　of　aliphatic　quaternary　ammonium　moiety.　©　CSIRO　2007.
