Abstract

We present three new hybrid layered lead(II) bromide perovskites of generic composition A2PbBr4 or AA′PbBr4, which exhibit three distinct structure types. [TzH]2PbBr4, ([TzH+]= 1,2,4-triazolium), adopts a (001)-oriented layer structure, [AaH]2PbBr4, ([AaH+] =acetamidinium), adopts a (110)-oriented type, whereas [ImH][TzH]PbBr4, ([ImH+] =imidazolium),adopts a rare (110)-oriented structure with enhanced corrugation (i.e. ‘3 ×3’ type). The crystal structures of each are discussed in terms of the differing natureof the templating molecular species. Photoluminescent spectra for each are reported and the behaviours discussed in relation to the different structure of each composition.
