Self-assembly of long-chain quaternary ammonium cations in a hybrid inorganic–organic material with one-dimensional polymeric tribromidoplumbate(II)

Abstract

catena-Poly[benzyldecyldimethylammonium [plumbate(II)-tri-μ-bromido]], {(C19H34N)[PbBr3]}n, crystallizes as an inorganic–organic hybrid following monoclinic space-group symmetryP21/c. The structure consists of extended chains running along the [001] direction and built of [PbBr3]−units. These inorganic chains are separated by interdigitated ammonium cations which form hydrophilic layers through weak C—H...Br interactions. The architecture is essentialy the same as found forn-alkylbenzyldimethylammonium bromides.
