Four new hybrid lead(II) halide perovskites, γ‐(FA) 2 PbBr 4 , (FA) 1.5 (AA) 0.5 PbBr 4 , (PY)(GA)PbBr 4 and (PY)(TZ)PbBr 4 ((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 [PbBr 4 ] ∞ 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.
