The variation of charge density at the Jahn-Teller transition of RbMn[Fe(CN)6] was investigated. The maximum entropy-Rietveld method combined with synchrotron radiation x-ray powder diffraction was used for the study. The origin for the anisotropic bonding electron distribution around the Mn3+ ion in the low-temperature phase was also discussed. The results show a charge transfer from the Mn site to the Fe site in the low-temperature phase.
