Octakis(3-propylammonium) octadecaiodopentaplumbate(II): a new layered stucture based on layered perovskites.
The title compound, (C3H10N)8[Pb5I18], crystallizes as an inorganic-organic hybrid. As such, the structure consists of two-dimensional sheets of corner- and face-sharing [PbI6]4- octahedra, separated by layers of 3-propylammonium cations, which hydrogen bond to the I atoms. The asymmetric unit contains six independent Pb atoms; four are on general positions and the other two are on special positions, viz. a centre of inversion and a twofold axis. The inorganic sheets show a never before seen motif.
