Figure 17. Parallel and perpendicular MSRDs for the Ga-N and Fe-C bonds [panels (A) and (B), respectively] of GaFe(CN)$$ _{6} $$. Panel (C) shows the resulting anisotropy of the relative thermal vibrations. Both Ga-N and Fe-C bonds display large transverse relative vibrations and contribute to NTE. However, it can be observed that the main contribution comes from the Ga-N thermal vibrations. Figure taken from Ref.^[114]. © ACS Publishing. Reproduced with permission. All rights reserved.
