Structural properties of two inequivalent Cs(1) and Cs(2) sites in perovskite tricaesium pentahalogencobaltate, Cs3CoX5 (X = Cl, Br)

AIP Advances, 2017
The local structures of Cs3CoX5 (X = Cl, Br) were examined using nuclear magnetic resonance (NMR) and magic angle spinning (MAS) NMR experiments. The two inequivalent Cs(1) and Cs(2) sites in two compounds were clearly distinguished based on static NMR ...
