Abstract

We present the new homologous series (C(NH 2 ) 3 )(CH 3 NH 3 ) n Pb n I 3 n +1 ( n = 1, 2, 3) of layered 2D perovskites. Structural characterization by single-crystal X-ray diffraction reveals that these compounds adopt an unprecedented structure type, which is stabilized by the alternating ordering...
