The pursuit of structure-property relationships in crystalline metal halide perovskites (MHPs) has yielded an unprecedented combination advantageous characteristics for wide-ranging optoelectronic applications. While MHP structures are readily accessible through diffraction-based structure refinements, providing a clear view associated long-range ordering, the local more recently discovered glassy states remain unexplored. Herein, we utilize Raman spectroscopy, solid-state nuclear magnetic resonance (NMR), Fourier transform infrared situ X-ray diffraction (XRD) and pair distribution function (PDF) analysis to investigate coordination environment crystalline, glass melt 2D [(S)-(-)-1-(1-naphthyl)ethylammonium]
