Abstract

Four new hybrid lead(II) halide perovskites, γ-(FA)₂PbBr₄, (FA)_1.5(AA)_0.5PbBr₄, (PY)(GA)PbBr₄ and (PY)(TZ)PbBr₄ ((FA)=formamidinium, (AA)=acetamidinium, (PY)=pyrazolium, (GA)=guanidinium and (TZ)=1,2,3-triazolium), adopt (110)-oriented layered perovskite structures. While (PY) is found to template the formation of ‘conventional’ (110)-oriented structure types (i. e. containing staggered [PbBr₄]_∞ layers), (FA) is shown to facilitate formation of much less common variants based 3 : 1 ordering of the interlayer species or 3×2 step-like corrugation of the perovskite-like layers themselves.
