Abstract

Abstract Thermal expansion of materials is a comparatively easy‐understood physical property. Prussian blue analogues are of particular interest in engineering as new zero thermal expansion materials. We investigated the thermal expansion in K 0.46 Co 1.27 [Fe(CN) 6 ] · 5.5H 2 O by x‐ray powder diffraction. This compound is a good example of a zero thermal expansion material. The origin of zero thermal expansion is considered to be the low frequency transverse vibrational motion of the cyano bridges.
