Abstract

The hybrid perovskites (ImH)(GuH)PbBr₄ and (TzH)(GuH)PbBr₄ (ImH⁺ = imidazolium, GuH⁺ = guanidinium, TzH⁺ = 1,2,4-triazolium) both adopt (110)-oriented layer structures. However, the GuH⁺ cation adopts differing crystallographic sites in the two structures (intra-layer versus inter-layer); this is discussed in terms of the sizes of the organic cations and their hydrogen-bonding preferences.
